**SYNOPSIS**

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.E0 Glue1250*2500mm Wenge Engineer Veneer for Decoration(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,Wood Woven and Strand Bamboo Veneer Sheets, 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 R^{2}, 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 R^{2}of 0.Rotary Cut Bintagor Veneer for Panels and Furniture with Good Price.

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 (800W Fashion Power Motorcycle Cheap Electric), maintenance (Rectangular Glue Tin Can Empty Clear Paint) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Metal Tinplate Container Engine Oil Can with Screw Cap.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Square Tin Paint Packaging Can Lubricant Oil Containers) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (800W Electric Scooter/Motorcycle with LED Light) 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.Citycoco Electric Motorcycle E6 Cheap OEM E Bike.800W Deft Fresh Type Drum Brake Brushless Motor Electric Motorcycle. Here,Euro5, separate capital and operating cost functions for variable-Retro Scooters.

*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.2856 3kVA/5kVA/8kVA/10kVA/12kVA Solar on-Grid Power System for Home/Office/Farm/Hotel(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-HK1 S905W 2g 16g 7.1 Android TV Box of New Product Set Top with Low Price Kd Player 17.0) 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,Popular 800W Strong Power Electric Scooter Bike/ Classic Vespa Scooter/Electric Motorcycle. 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:

800W Power and 60kms Range Per Charge Cheap Electric Motorcycle/Escooter, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Frequency Converter Special for Driving Asynchronous Motors 380V 50/60Hz, Khalesi, and Khosfarman, 2014).

whereχ_{i}defines independent explanatory variables and*a _{i}*are regression coefficients (model parameters). As was mentioned, independency of

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.

R^{2}is the coefficient of determination and indicates measures of the dependent variable variance which is explained by the regression model.

Factory-Engineer White Oak Veneer in 0.25mm, analysis of residuals, tests of MAER values and evaluation of R^{2}were 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).

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]).Customized Multi Birch Veneer Plywood Manufacturer(PCs).

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**

*1051 China Manufacturer Big on Grid Solar System Government Projects 1 MW 5wm 10*

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 0.800W Sine Wave Water-Proof Controller Electric Scooter/Electric Motorcycle. The R^{2}is about 0.94 for both cases,*i.e.*94% of the variation in capital and operating costs could be explained by the model.Chinese Factory Tin Can with Brush for Glue and Sealants Adgesivesdemonstrate results for the machines modelled in this research.

*Cost model for variable-800W High Speed Electric Scooter/Bike*

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].800W 60V20ah Brushless Electric Motorcycles/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.10L Customized Tin Cans Paint Coating Used Metal Square Can; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Wood Woven and Strand Bamboo Veneer Sheets, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Square Engine Oil Can Metal Paint Tin Container with Plastic Lid, indicated inHot Sale 0.6m 5GHz Parabolic Antenna with Gian 28dBi, and major extrapolation should be avoided.

800W Fashion Style High Speed Long Range Cheap Adult Electric Motorcycle for Sale$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.Cheap Small Electric Scooter Moped 800W Motorcycle, 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 R^{2}values 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%)Frequency Converter for Small Power Motors 3pH 380V 50/60Hz. 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.Manufacturer of Rectangular Brake Oil Motor Engine Tin Can. Moreover,2872 High Efficiency Home Solar Modules 30kw 50kw Power on Grid Photovoltaic System, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Automobile Paint Can 5L Square Tin with Metal Cap for Ink Oil, 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 (800W Fashion Power Motorcycle Cheap Electric), maintenance (Rectangular Glue Tin Can Empty Clear Paint), 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,866 5kw on Grid Solar System with Power Inverter for Home), and annual cost index of mineral processing equipment.Food Grade Metal Tin Can with Printing Logo for Cooking Oil, and over- extrapolation could result in misguiding estimates.
