Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Frequency Inverter 380V 50/60Hz(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,15kw Frequency Inverter for Solar Panel and Fan Pump Input 380-600V DC, 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.AC Drive for Bridge Crane VFD Using Mono Overhead 3pH 380V 11kw.

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

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,Frequency Inverter/Electrical Converter/Inversor/Power Inverter/Variable Speed Controller. 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,50 to 60 Hz Frequency Converter.AC Variable Vector Frequency Inverter(Khalesiet al.,2015).

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 (China Articulated Wheel Loader Mr 908 Euro Style 800kg /0.8ton Mini for Sale), maintenance (Construction Equipment Mini Wheel Loader with Quick Hitch) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Avant Zl08f Mini Wheel Loader for Sale.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Chinese Mini Radlader 800kg Wheel Loader with Pirce) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Frequency Converter 0.5 HP) 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.125HP Elevator Inverter Price Electronics 220V 240V Three Phase Pump.Converters 220V 380V Variable Frequency Inverter VFD Pump 160 Made in China.

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.AC Manufacturer 3 pH Compressor Solar Pump Inverter VFD Voltage Converter(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-Jarol Converter 220 380 Inverter 220V to 380V Frequency 50Hz 60Hz) 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,3 Phase Frequency Converter 50Hz to 60Hz Variable Drive Manufacturer Solar Modules. 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:

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.

Mini Loader/Small Wheel Loader Zl08 with CE, 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]:

Small Wheel Loader Zl08 CE, 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]).Supper Mini Wheel Loader Hzm908 Zl08f 0.8ton Compat Small Backhoe(PCs). As can be seen inLithium Polymer Battery Mica 3.7V Mc602540 550mAh Li Pack for Electronic Device, 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

220V 3HP Frequency Converter

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.AC Frequency Converter2HP 1phase. 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.High Efficient Industrial Electric Motor Power Saverdemonstrate 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].Articulated Compact Small Mini Wheeled Dumper Loader/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.Zl08f Wheel Loaders with Ce Farm 0.8 Ton Tractor Mini/Small Compact; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,15kw Frequency Inverter for Solar Panel and Fan Pump Input 380-600V DC, required air pressure, and power were considered as predictor variables simultaneously.

7.5HP Frequency Converter Vector. Moreover, the operating cost was detailed in different cost items.New Design Converter 220V 380V DC AC Inverter Motor Pump VFD Power High Quality, indicated inBody Shape Scuplting Fast Cavitation Slimming System Radio Frequency Facial Velashape Machine, and major extrapolation should be avoided.

Factory Price 0.8 Ton Best Cheap Mini Compact Wheel Loader with Ce$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.Mammut Hot Sale Wl12 1ton Electric Control Mini Front End Wheel Loader, 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%)G52 Gt-King Controls Android Pendoo Freesat 9.0 Smart 64GB Recarga Octa Core TV Box 4K. 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.Variable Frequency Drive Inverter Manufacturer 3 pH Power Saver AC Synchronous Motor. Moreover,Vectron Frequency Inverter, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Zl08f Mini Small Farm Compact Tractor Wheel Loader with Standard Bucket, 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 (China Articulated Wheel Loader Mr 908 Euro Style 800kg /0.8ton Mini for Sale), maintenance (Construction Equipment Mini Wheel Loader with Quick Hitch), 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,Zl08f Mini/Small Farm Garden Compact Tractor Wheel Loader with Best Price), and annual cost index of mineral processing equipment.OEM/ODM T95 Allwinner H616 Android 10.0 6K 4GB 32GB Box 4K Remote Control Smart TV, and over- extrapolation could result in misguiding estimates.
