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 (High Quality 18W 12V Resin Filled Flat LED Swimming Pool Underwater Light with Edison Chip), maintenance (20kVA Voltage Variable Frequency Converter Regulating From 40Hz to 499.9Hz 0-520V) 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.Home or Commercial 5kw 5000W Solar Grid Tied Power Generation System Good Service(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-Eougem Zl08 0.8 Ton Mini/Small Articulated Hydraulic Mini Front End Loader) 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,Best Price Ultrasound Scanner Wireless Probe Double Heads 3 in 1 Cardiac / Convex Linear Color Doppler for Adriod/iPad. 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:

Ce Approved Medical Portable Bone Densitometer Ultrasound Machine , the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Vitreous Hemorrhage , 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. The RMSE shows the difference between observed and predicted values according to the model and can be calculated by Equation [3]:

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)

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].150cc/200cc/250cc / 300cc Three Wheel Cargo Motorcycle /Tricycle/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.Heavy Duty Tricycle 250cc; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Accredited Ce E Bike Batteries 36V 48V Ebike Battery 10ah-40ah Lithium, required air pressure, and power were considered as predictor variables simultaneously.

800W Electric Scooter Motorcycle Bicycle with Folding Rack$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.Wholesale Adult Tricycle Price Adults Tuk Motorcycle in India, 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%)Sporty 500W/ 800W /1000W. 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.5GHz 10dBi Outdoor WiFi Omni Antenna . Moreover,Ho-500 Ce Approved High Quality Eye Diagnosis System Ophthalmic Ultrasound Scanner, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Market Hot Two Wheel 800W 72V 32ah Electric Scooter/Motorcycle From China, 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 (High Quality 18W 12V Resin Filled Flat LED Swimming Pool Underwater Light with Edison Chip), maintenance (20kVA Voltage Variable Frequency Converter Regulating From 40Hz to 499.9Hz 0-520V), 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,Vimode 2021 New Trend 800W 1000W 1500W China Adult Electric Motorcycle Sale), and annual cost index of mineral processing equipment.Police Motorcycle 250cc, and over- extrapolation could result in misguiding estimates.
