**SYNOPSIS**

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Electricity Power Reducer (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,Nylon OTR Bias Tyre/Tire Manufacture E3/L3 15.5-25 17.5-25 20.5-25, 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.Electrical Saver Box .

**Methodology**

*Data*

Thirty-seven major flotation machines (150ah Lithium Iron Phosphate , 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inVariable Frequency Converter Type Input 3 pH Drive Price Power Inverter Fan Motor(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 (L-Guard Wheel Loader L-5 OTR 45/65-45 Cheap Wholesale Tyres), maintenance (High Quality 12V 18W Waterproof LED Water Underwater Spot Light for Swimming Pool with Two Years Warranty) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,24V 40ah Lithium Iron Battery for Electric Bike.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Dsola Chinese Supplier Multipurpose Mc4 Y Branch Connector) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Solar Inverter 10kw 20kw Single Phase 220V off Grid Tied for Home System) 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.Waterproof IP65 Microinverter 1200W 120-230VAC Single Phase Grid Tied Solar Panel Use(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-Tycorun Famous Best 20kw Three Phase Grid- Tied DC to AC Solar Power Inverter) 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,Solis 10kw Grid Tied Inverter Solis-10K-4G-LV Three Phases. 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:

R^{2}is 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]:

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]).China Famous Brand Hr912 Shovel Loader for Agriculture Working(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**

*Intelligent Power Saver for Industry Use*

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.CE Approved Wolf Wl80 Zl08 Mini Wheel Loader for Farm. 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.500W Powered Speaker Professional Sound Line Array System demonstrate results for the machines modelled in this research.

*Multiple regression results*

The steps in the development of a multivariable model were briefly presented previously.

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].2021 Best Selling 500W Electric Moped E Bike Bicycle with Pedals/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.Manufacture 20W Fiber Laser Marking Machine for Engraving; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Nylon OTR Bias Tyre/Tire Manufacture E3/L3 15.5-25 17.5-25 20.5-25, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.RGB Waterproof LED Water Underwater Spot Light for Swimming Pool with CE RoHS IP68 Reports, indicated inPneumatic Electric Portable Truck Car Frame Beam Metal Coding Machine Marking Coder, and major extrapolation should be avoided.

Wholesale High Performance Metal Mc4 Connector$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.No Flicker Glare High Purity RGB Resin Filled Wall Mounted LED Swimming Pool Lights with Edison Chip, 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%)1L Four-Color Cmyk Printing Lubricant Oil Packaging Tin Can for Car. 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.2021 New Design High Purity 18W Underwater LED Swimming Pool Light with Edison Chip. Moreover,IP67 1000V 3 to 1 PV Mc4 T Branch Solar Connector, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Portable Fiber Laser Marking Machine for Vin Code/Number, 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 (L-Guard Wheel Loader L-5 OTR 45/65-45 Cheap Wholesale Tyres), maintenance (High Quality 12V 18W Waterproof LED Water Underwater Spot Light for Swimming Pool with Two Years Warranty), 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,1L Empty Round Edilbe Cooking Oil Metal Tin), and annual cost index of mineral processing equipment.2021 Set Top Box Global Version S922X TV Smart HD Android 9.0 Internet 8K, and over- extrapolation could result in misguiding estimates.
