**SYNOPSIS**

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.High Efficient Industrial Electric Motor Power Saver(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,EEC 125/300cc Euro 5V Max Scooter-Alex One, 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.Electricity Power Reducer .

**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,Electrical Saver Box . 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,Sector Panel Antenna .15.5-25 17.5-25 20.5-25 23.5-25 OTR Tire(Khalesi*et al.,*2015).

**Methodology**

*Data*

Thirty-seven major flotation machines (5.8g Omni Antenna/Dual Frequency Antenna 2.4G 5.8g/2400-2500MHz Omi, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inCheap Electric Scooter 500W Pedal Bicycle 25km/H for Export(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 (4000W/5000W off Grid Tied Solar Power System), maintenance (Internet TV Box Linux IPTV Zgemma I55) and lubrication cost items.

*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.2074 Growatt Inverter 9kw on Grid 9000W Tied Solar Power System Home(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 Famous Brand Canmax Wheel Loader Cm908 Using Hydraulic Pump Machinery Can Be Used in Farms) 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,Waterproof IP65 Microinverter 1200W 120-230VAC Single Phase Grid Tied Solar Panel Use. 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:

Solis 10kw Grid Tied Inverter Solis-10K-4G-LV Three Phases, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (New Pattern Design 17.5-25 20.5-25 26.5-25 off Road Tyre, 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.

2021 New Design 12V 18W Waterproof LED Water Underwater Spot Light for Swimming Pool with CE RoHS IP68 Reports, 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).

*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]).15kw Solar Inverter Grid Tied(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)

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.China Factory Lithium 150ah Battery with BMS AC Output. 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.Live Music Sound Line Array System for Acoustic and Electronic Performancedemonstrate 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].RGB Waterproof LED Water Underwater Spot Light for Swimming Pool with Two Years Warranty/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.Made in China Strong Compact Mini Front Loader ; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,EEC 125/300cc Euro 5V Max Scooter-Alex One, required air pressure, and power were considered as predictor variables simultaneously.

3kw Air-Cooled UHF Digital TV Transmitter DTV$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.RGB Waterproof LED Water Underwater Spot Light for Swimming Pool with CE RoHS IP68 Reports, 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%)Wholesale High Performance Metal Mc4 Connector. 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.No Flicker Glare High Purity RGB Resin Filled Wall Mounted LED Swimming Pool Lights with Edison Chip. Moreover,1L Four-Color Cmyk Printing Lubricant Oil Packaging Tin Can for Car, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (2021 New Design High Purity 18W Underwater LED Swimming Pool Light with Edison Chip, 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 (4000W/5000W off Grid Tied Solar Power System), maintenance (Internet TV Box Linux IPTV Zgemma I55), 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,IP67 1000V 3 to 1 PV Mc4 T Branch Solar Connector), and annual cost index of mineral processing equipment.Portable Fiber Laser Marking Machine for Vin Code/Number, and over- extrapolation could result in misguiding estimates.
