**SYNOPSIS**

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.1HP Frequency Converter Vector Three Phase(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,15HP Frequency Converter Vector Three Phase, 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 0.2HP Frequency Converter Vector Single Phase.

**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,Home Use 6kw Grid Tied Solar Power System with High Performance. 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.

Thirty-seven major flotation machines (Power Mini Electric Scooter for Lady 60V800W, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inChinese Factory for Vitamin a Palmitate 0.25miu Powder(InfoMine, 2013).

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 (Wholesale 947 Ml/32oz Metal Round Glue Can Tin with Brush Cap), maintenance (500ml 16oz Round Metal Glue Tin Can with Screw Top Brush for Chemical) and lubrication cost items.

The overhaul costs (Customized B/C/D/E Grade Wood/Natural Birch Veneer) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (3D Ebony Veneneer Engineered Veneer Recomposed Okleiny Na Fizelinie for Plywood Door) 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.Bulk Quality Cheap Smart Elecetric Scooter 60V800W for Lady(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-Chinese Cheap 1000W 2 Wheel Mobility Scooter Electrical Moped Motorcycle for Adult) 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,350-1000W Pedal Assist Electric Scooter Parts 10 Inch Mobility Tricycles Motorcycles Chinese for Adults. 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:

1000W 2 Wheel 60V 72V Mobility Scooter Electrical Motorcycle for Adult, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Chinese Best Cheap Electric Scooter Korea Hot Sell 48V Thailand Motorcycle with Pedal, Khalesi, and Khosfarman, 2014).

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)

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 0.60V/72V 1200W Electric Scooter with Tianneng Battery.

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].Frequency Inverter Pump AC Drive Price/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.Frequency Inverter VFD AC Drive; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,15HP Frequency Converter Vector Three Phase, required air pressure, and power were considered as predictor variables simultaneously.

Power Frequency Converter AC Drive Inverter$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.Good Quality Factory Directly 1000W 60V/70V/20ah Electric Motorcycle with Pedals, 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%)0.5L Tin Can with Dry Cover. 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.Food Grade Container 1 Liter Square Olive Oil Latest Design Metal Tin Cans. Moreover,AC Frequency Converter 50Hz 60Hz Drive Inverter, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Good Quality Electric Bike & Two-Wheel Dual Motor Foldable China Motorcycle for Adult, 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 (Wholesale 947 Ml/32oz Metal Round Glue Can Tin with Brush Cap), maintenance (500ml 16oz Round Metal Glue Tin Can with Screw Top Brush for Chemical), 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,Food Grade 3 Liter Square Olive Oil Tin Can with Handle and Cap), and annual cost index of mineral processing equipment.Cheap Power Motor Big Protect Frame Electric Scooter Motorcycle 60V800W, and over- extrapolation could result in misguiding estimates.
