SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.21% Fertilizer Ammonium Sulphate Caprolactam Grade Crystalline(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,Agriculture Fertilizer Nitrogen 21% Ammonium Sulfate China Factory, 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.Power Steel Grade Nitrogen 20.5% Industrial Ammonium Sulphate Chemical Fertilizer.

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

Introduction

White Extrusion Granular Ammonium Sulphate China Factory, 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,Granular Grade Ammonium Sulphate N20.5% Nitrogen Fertilizer. 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.

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 (T250-04 452055-5004s Turbocharger for Gemini III Engine), maintenance (Gtb1749vk Turbo Cartridge 798128-0004 for 2011- Peugeot Boxer) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Gt3776D 466819-5004s 1823560c92 Turbo for Ford F650 Navistar.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Gt1749vk 798015-0002 A6710900380 Turbo for Ssang-Yong Korando C200 2.0 D20dtf Engine) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Gt1544V 740611-5002s 28201-2A400 Turbo for Hyundai Verna) are associated with both unscheduled repairs and scheduled servicing of all of minor and major components, excluding overhaul actions and lubrication.

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.L-Pyroglutamic Acid(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-Dl-Isoleucine Powder CAS Number 443- 79 -8) 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,98% Uvarigranol B\C\D\E Standard Reference Materials Plant Extracts. 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:

Ademetionine Disulfate Tosylate , the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Centella Asiatica Extract 99% Asiaticoside 16830-15-2, Khalesi, and Khosfarman, 2014).

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.

Crovell Supply Raw Material CAS 104-29-0 Chlorphenesin for Cosmetic, 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]:

Polyethylene Green Color Masterbatch, 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]).ISO Certificated Company Supply Skin Whitening Retinoic Acid Powder(PCs). As can be seen inCAS No.: 67-63-0 Isopropyl Alcohol 99.9%/Ipa 99.9%/Isopropanol 99.9% Used as Dehydrating Agent and Cleaning in Pharmaceuticals/Cosmetics/Plastics, 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

Yellow HDPE Masterbatch

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.Universal LPG Gas Completed ECU Conversion Kit. 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.Customized Metal Tea Canister Food Packaging Box Round Can Tindemonstrate 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].Fuel Gas Cylinder ECU 2568d Map Sensors/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.Motorcycle Act 2568d 6cyl 8cyl ECU Conversion Kit; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Agriculture Fertilizer Nitrogen 21% Ammonium Sulfate China Factory, required air pressure, and power were considered as predictor variables simultaneously.

Auto Vehicle Gas Conversion Kit CNG Seqential Injection Kits. Moreover, the operating cost was detailed in different cost items.Electric Pipe End Bevelling Machine, indicated inFactory Supply Disodium Phosphate Food Grade, and major extrapolation should be avoided.

T-Electric Pipe Bevelling Machine $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.Pneumatic Pipe Beveling Machine High Performence, 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%)Act CNG LPG Fuel System 2568cyl ECU Kits. 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.Factory Directly Sell Good Performance Virgin Transparent PA12 Granules/Pellets /Polyamide 12 Resin for Oil Cup. Moreover,Plastic Green Color Masterbatch, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (4 Cyl CNG Auto Gas LPG Conversion Kit / Sequential Injection System, 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 (T250-04 452055-5004s Turbocharger for Gemini III Engine), maintenance (Gtb1749vk Turbo Cartridge 798128-0004 for 2011- Peugeot Boxer), 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,3cyl 4 Cyl 6cyl 8cyl LPG/CNG Injector Rail), and annual cost index of mineral processing equipment.L Auto Gas LPG Conversion Kit / Car 4 Cyl Sequential Injection System, and over- extrapolation could result in misguiding estimates.
