Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.High Quality Aod-9604 CAS 221231-10-3 Aod 9604 Peptides 2mg for Loss Weight(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,CAS 79 -57-2 Oxytetracycline, 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.Azd3759 CAS No. 1626387-81-2.

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

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.15inch Professional Stereo Sound PA PRO Audio DJ Loud Speaker(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-Professional Line Array PA System S1210 Sound) 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,Cosmetic Material 99% Purity Tretinoin Powder. 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:

Spts, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (High Power DJ Sound Equipment System Line Array PA Speaker, 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.

2X12 Outdoor Compact Neodymium PRO Audio PA Event Line Array, 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.

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]).Factory Supply Topiramate Antiepileptic Drug with Best Price CAS No 97240- 79 -4(PCs). As can be seen inJ8 Dual 12'' Line Array PA Speaker Professional Stage Audio System, 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)

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].Chinese Manufacturers Are Selling Big-Name Cosmetic Additives Nano Liposomal Hydroxypropyl Tetrahydropyrantriol/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.


Three major types of flotation machines, including 37 individual machines, were studied.Professional Line Array Speaker Neodymium Af15; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,CAS 79 -57-2 Oxytetracycline, required air pressure, and power were considered as predictor variables simultaneously.

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.Professional 24 Channels Digital Audio Mixer Console, 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%)100% Natural Huperzia Serrata Extract 1% 5% 99% Huperzine a Brown Powder Supplements. In the MRA cases, this property is owed to the SFM (3.05%).


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.Skin Care Raw Material Vitamin a Palmitate Powder. Moreover,Lf Drivers 10 Inches Professional Speaker Pw1032-64, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (12" Loudspeaker as Monitor Speaker System 12 Inch Powerful Coaxial, 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 (Chlorhexidine Diacetate CAS No 206986- 79 -0), maintenance (CAS 79 -14-1 Glycolic Acid 70%), 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,Made in China PA Speaker System Three Way Loudspeakers), and annual cost index of mineral processing equipment.Line Array Speaker Professional PA System Two Way Full Rang Passive , and over- extrapolation could result in misguiding estimates.
