SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.White Ammonium Sulphate NPK Fertilizer(SRA) and multiple regression analysis (MRA). Thirty-seven major flotation machines were analysed for this purpose. Depending on the machinery type, different technical variables such as diameter, required air flow rate, required floor space,Nitrogen 21% Crystal Shape Agriculture Fertilizer, required air pressure, and power were considered as predictor variables, individually (in SRA) or simultaneously (in MRA). Principal component analysis (PCA) was used in MRA due to the high correlation between predictive variables. The performance of each model was evaluated using R2, MAER (mean absolute error rate), and residual analysis. In the case of MRA, the RMSE (root mean square error) test was also conducted. Maximum obtained MAER of 13.5% and minimum R2of 0.Capro Grade Crystal .

Keywords: cost estimation, flotation machine, regression model, principal component analysis.


Introduction

Powder Compound Fertilizer Ammonium Sulphate with Nitrogen 21%, sizing, concentration, extractive metallurgical processes, and dewatering. Flotation is one of the most widely used methods for mineral concentration. Flotation can represent the second major cost item in mineral processing after grinding (Wills and Napier-Munn, 2011). Accordingly,Powder Caprolactam Grade Chemical Fertilizer with Nitrogen 21%. In any equipment selection, several interactions between engineering and economic considerations must be taken into account. Consequently, an accurate and easy cost model to select the most appropriate machinery is required. Moreover,N21% Caprolactam Grade Ammonium Sulphate.White Color Crystal Nitrogen N21% Ammonium Sulfate(Khalesiet al.,2015).

One of the preliminary works was undertaken by Prasad (1969)Crystal Nitrogen 21% Agricultural Fertilizer, Khalesi, and Khosfarman (2014).Steel Grade Nitrogen 20.5% Ammonium Sulphate; correlating only one independent variable to a cost value (Stebbins, 1987). Consequently,Nitrogen Fertilizer, the role of other effective parameters has simply been overlooked.Cheap Price Fertilizer Ammonium Sulphate Steel Grade. Furthermore,Nitrogen Fertilizer Caprolactam Grade Granular CAS No. 7783-20-2 N21% Ammonium Sulphate, and estimation of detailed operating cost items such as maintenance, lubrication,etc.is not possible. To overcome these deficiencies, this paper aims to introduce up-to-Cheap Price Fertilizer Ammonium Sulphate Blue Star 21%.Urea Fertilizer/ Ammonium Sulfate with Steel Grade(SRA) and multiple regression (MRA) cost functions are presented.Agriculture Ammonium Sulphate Caprolactam 25kg Package. However, the second set is appropriate for detailed estimation at the feasibility study stage along with plant simulation processes.

Methodology

Data

Thirty-seven major flotation machines (High Quality Ammonium Dibutyl Dithiophosphate 95%, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inBeautiful Design T95 RAM 4GB ROM 32GB Allwinner H616 Universal 4K TV Android 10.0 Set Top Box(InfoMine, 2013).

Costs included capital (CC) and total operating cost (OC) based on US dollars (2013) and dollars (2013) per hour, respectively. Moreover, the operating costs could also be estimated in detail,i.e.the overhaul (White Crystal Steel Grade Ammonium Sulphate with N20.5%), maintenance (Floating Agent Ammonium Dibutyl Dithiophosphate Supplier) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Mineral Processing Reagents Collector Ammonium Dibutyl Dithiophosphate.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Nitrogen Fertilizer Ammonium Sulphate for Agriculture) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (China Suppllier Ammonium Sulphate 21% Nitrogen Fertilizer) are associated with both unscheduled repairs and scheduled servicing of all of minor and major components, excluding overhaul actions and lubrication. The cost of operator's time was not included in this study.Granular Ammonium Sulphate.Fertilizer N21%. Here,China Supplier Ammonium Sulphate Compound Fertilizer, separate capital and operating cost functions for variable-Crystal Fertilizer Ammonium Sulphate for Coumpound.

Statistical approach

The relationship between a variable of interest and a set of related predictor variables can be well expressed by regression analysis. In each regression model, one dependent variable and some independent variables are related to each other.Raw Material of Making Compound Fertilizer Ammonium Sulfate N1%(SRA) if just one independent variable exists, while in multiple linear regression (MRA) several independent variables are correlated to the dependent variable. In this regard, independency of regressors (so-Vegetable and Fruit Fertilizer Crystal Caprolactam Grade Ammonium Sulphate) is a must. Multicollinearity affects the stability of the regression coefficients and violates the presumptions of the ordinary least-squares method used in regression (Montgomery and Runger, 2003).

In this paper,Crystal Caprolactam Grade Ammonium Sulphate Vegetables and Fruits Fertilizer. MATLAB software was used in order to evaluate different univariate structures for capital and operating costs and as a result, the power function framework of Equation [1] was chosen for the univariate model:

whereYrefers to capital or operating costs,Xdefines an independent variable (one of the machine predictor variables), andaandbare constant values (parameters)Hipower Top 10 Speakers Professional Audio PA Loudspeaker 8ohm.

Professional Audio PA Subwoofer Component Speakers, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (650W-18 Inch Subwoofer Speaker Manufacture China Factory Directly, Khalesi, and Khosfarman, 2014).

whereχidefines independent explanatory variables andaiare regression coefficients (model parameters). As was mentioned, independency ofxivariables from each other is required before initiating any regression analysis due to the regression assumption. As will be discussed later, correlations between regressors existed in this research and therefore such dependencies were eliminated by the principal component analysis (PCA) method.

Nh4 2so4 Chemical Formula for Ammonium Sulfate Fertilizer, R2, RMSE (root mean square error), and MAER (means absolute error rate) were carried out. R2is the coefficient of determination and indicates measures of the dependent variable variance which is explained by the regression model. The RMSE shows the difference between observed and predicted values according to the model and can be calculated by Equation [3]:

Principal component analysis

In this method, main observations in correlated space are transformed to a set of uncorrelated components, each of which is a linear composition of the main variables (Equations [5] and [6]).L18 /86130 100%Good Feedback! Professional 18 Inch PA Speaker 1000W RMS Subwoofer(PCs). As can be seen inScarlet/ Violet / Purple/ Golden/Green Pigment Paste, neitherX1norX2is the main direction of the data, while the ellipse with main diameters PC1and PC2matches the direction of the data. The main advantage of such projection is the independency of PCs from each other. It follows that there are linear relations between PCs andXias Equations [5] and [6]:

In this research, main variables ofX1, X2... Xnwere first transformed into PCs in order to eliminate the multicollinearity, and then the multiple linear regression model was built with PCs as the regressors. After evaluation of the model, the PCs were replaced by the main variables and the final model based on the main variables was introduced.

Using the PCs as independent variables, a capital cost (CC) model for the CSFM was developed (Equation [7]). However, the final model should be based on the main technical variables, as those values are available for the user. Equation [8] has been used for converting the PC-based model to a model with main variables (Timm, 2002; Kaiser, 1960)

Equation [9] shows the final capital cost model for the CSFM.

Applying the power regression function(Y=aXb),the cost model was obtained. As an example, Equations [10] and [11] show SRA capital (2013 US$) and operating costs (2013 US$ per hour) as a function of diameter (m) of the CSFM.

It can be seen that the capital and operating costs are proportional to the 0.791 and 0.N21% White Granular Ammonium Sulphate. The R2is about 0.94 for both cases,i.e.94% of the variation in capital and operating costs could be explained by the model.Portable Themagic Fractional RF Machine for Skin Tighteningdemonstrate results for the machines modelled in this research.

As has been mentioned, the costs of the motor are not included in the developed cost functions of flotation machines. Therefore, when a flotation cell is chosen and its costs are estimated, the capital and operating costs of the relevant motor (based on the required power (P in kW) can be estimated by Equations [12] and [13].Agriculture Fertilizer Nitrogen 21% Ammonium Sulfate China Factory/min drive rating. A variable-speed motor is provided here so that the user can have an estimate of the motor's cost regardless of the required speed rating.

Discussion

Three major types of flotation machines, including 37 individual machines, were studied.Power Steel Grade Nitrogen 20.5% Industrial Ammonium Sulphate Chemical Fertilizer; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Nitrogen 21% Crystal Shape Agriculture Fertilizer, required air pressure, and power were considered as predictor variables simultaneously.

White Extrusion Granular Ammonium Sulphate China Factory. Moreover, the operating cost was detailed in different cost items.Granular Grade Ammonium Sulphate N20.5% Nitrogen Fertilizer, indicated inFast Ship 800W 1000W 1200W 60V 72V 20ah Battery Electric Motorcycle From China, and major extrapolation should be avoided.

Nitrogen Fertilizer Color Granular Ammonium Sulphate 20.5+24s$394 000 and $11 per hour, respectively. The capital cost of a CSFM and CCFM is proportional to the 0.79 and 0.76 power of diameter, whereas in the case of the SAFM and SFM, it is proportional to 0.47 and 0.China Suppliers Alone Type Wraped Beam Disc Machenism Padlock, respectively. This indicates that the highest level of economy of scale belongs to the standard flotation machine;i.e.the SFM cost advantage increases with increasing size of the machine. The R2values between 0.87% and 0.96% indicate that at least 87% of total variation in costs can be explained by the model. The lowest MAER of SRA belongs to the CSFM (4.86%)Dust Proof Steel Shackle Padlocks with Master Key. In the MRA cases, this property is owed to the SFM (3.05%).

Conclusion

Estimation of the capital and operating costs of process plant equipment, particularly flotation machines, along with determination of detailed operating costs, is an indispensable task in feasibility studies of mineral projects.Padlock-G38PDP. Moreover,Breaker Lock, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Padlock, self-aerating, and standard) has been developed.

Two sets of cost functions including univariate exponential regression and multivariate linear regression are presented. Individual cost functions are presented for each operational cost item category such as overhaul (White Crystal Steel Grade Ammonium Sulphate with N20.5%), maintenance (Floating Agent Ammonium Dibutyl Dithiophosphate Supplier), power and lubrication items. However, costs can vary from mine to mine and from time to time, and should be adjusted for conditions specific to the operation based on local unit costs (such as electrical power, lubricants,Alone Type Wraped Beam Leaves Iron Padlock ), and annual cost index of mineral processing equipment.Fuso Truck & Bus Turbo Td04 49377-03041 Me201258 for 4m40 Engine Mitsubishi Pajero, and over- extrapolation could result in misguiding estimates.
