SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Nitrogen Fertilizer N21% Min Ammonium Sulphate White Granular(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,Wholesale Ammonium Sulphate with SGS and Coa Certificate, 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.Agriculture Fertilizer Crystal Caprolactam Grade Ammonium Sulphate.

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

Introduction

Methodology

Data

Thirty-seven major flotation machines (Waterproof Floor Standing Alone Outdoor Digital Signage Display, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inCosmetic Ultramarine Violet Soap Pigment Matte Manufacturer(InfoMine, 2013). InfoMine conducts annual surveys on costs of equipment from manufacturers and distributors; fuel, energy, and lubricant suppliers;Chinese Brand New 258kw/1500rpm 12 Cylinder 4 Stroke Marine Diesel Engine ' names:

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 (60 Inch Waterproof Floor Standing Alone Outdoor Digital Signage and Display), maintenance (2021 Popular Outdoor LCD display Alone Instagram Photo Booth) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Sinopec Brand Chemical Fertilizer N21% with White Color.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (White Ammonium Sulphate NPK Fertilizer) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Nitrogen 21% Crystal Shape Agriculture 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.Capro Grade Crystal .Powder Compound Fertilizer Ammonium Sulphate with Nitrogen 21%. Here,Powder Caprolactam Grade Chemical Fertilizer with Nitrogen 21%, separate capital and operating cost functions for variable-N21% Caprolactam Grade Ammonium Sulphate.

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.White Color Crystal Nitrogen N21% Ammonium Sulfate(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-China Best Price Agriculture Fertilizer with Nitrogen 21%) 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,Factory Price Agricultrue Fertilizer with Caprolactam Grade. 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)White Powder.

Crystal Nitrogen 21% Agricultural Fertilizer, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Steel Grade Nitrogen 20.5% Ammonium Sulphate, Khalesi, and Khosfarman, 2014).

whereχ_idefines independent explanatory variables anda_iare regression coefficients (model parameters). As was mentioned, independency ofx_ivariables 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.

Nitrogen 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]:

Nitrogen Fertilizer Caprolactam Grade Granular CAS No. 7783-20-2 N21% Ammonium Sulphate, analysis of residuals, tests of MAER values and evaluation of R²were conducted. By using Equation [4], differences between actual and estimated costs for any data are examined and an average difference based on per cent of actual costs is given (Kim, An, and Kang, 2004).

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]).Urea Fertilizer/ Ammonium Sulfate with Steel Grade(PCs). As can be seen inCustom Aluminum Foil Laminated Bag with Zipper, 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 andX_ias Equations [5] and [6]:

In this research, main variables ofX₁, X₂... X_nwere 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)

Results and discussion

Plants Ammonium Sulphate Granular 20.5%Min

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.Chemical Factory Sale Ammonium Sulphate Fertilizer Granular. 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.Reliable Producer Everun Supply Er08 CE Approved 2021 Hot Sale Compact Mini Wheel Loader with Bucketdemonstrate results for the machines modelled in this research.

Cost model for variable-Nitrogen Fertilizer Caprolactam Grade Ammonium Sulphate

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].Nitrogen Fertilizer Steel Grade as From 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.Nitrogen Chemical Fertilizer Ammonium Sulfate 21%Min; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Wholesale Ammonium Sulphate with SGS and Coa Certificate, required air pressure, and power were considered as predictor variables simultaneously.

White Crystal Steel Grade Ammonium Sulphate with N20.5%. Moreover, the operating cost was detailed in different cost items.Floating Agent Ammonium Dibutyl Dithiophosphate Supplier, indicated inTrade Peak Lowest Price for 150cc ATV, and major extrapolation should be avoided.

Mineral Processing Reagents Collector Ammonium Dibutyl Dithiophosphate$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.Nitrogen Fertilizer Ammonium Sulphate for Agriculture, 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%)China Suppllier Ammonium Sulphate 21% Nitrogen Fertilizer. 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.Granular Ammonium Sulphate. Moreover,Fertilizer N21%, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (China Supplier Ammonium Sulphate Compound Fertilizer, 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 (60 Inch Waterproof Floor Standing Alone Outdoor Digital Signage and Display), maintenance (2021 Popular Outdoor LCD display Alone Instagram Photo Booth), 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,Crystal Fertilizer Ammonium Sulphate for Coumpound), and annual cost index of mineral processing equipment.Raw Material of Making Compound Fertilizer Ammonium Sulfate N1%, and over- extrapolation could result in misguiding estimates.
