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,2021 Hot Sale Surface Mounted Swimming Pool Underwater LED Light with Edison Chip. 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.

Methodology

Data

Thirty-seven major flotation machines (New Cooling Fast Racing Motorcycle 400cc 250cc Efi System 150km/H, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented inGlue Tin Can with Plastic Lid / Square Metal Paint Sizes(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 (High Speed Kawasaki Ninja Motorcycle 250cc), maintenance (Mini Nameplate Pneumatic Engraving Machine) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Electric Smart Cargo Car Tricycle 800W 40km/H Long Running Range.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Mini electric truck/ express vehicle/ Express vehicles) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Bost Motorcycle Parts Accessories Air Filter for 2-Wheel 4-Stroke Gy6 -125 -150 Bikes) 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.BAW Made of Electric Car with Lithium Battery.EEC L2e 1500W 3 Wheel Enclosed Electric Cabin Scooter.

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.4x2 electric pickup truck/ Electric vehicle/ car(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-Electric 4 Wheelers Cars 800W 50km/H Mini Old Man Tricycle ) 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,2021 New Products Motor Power 800W Electric Trolley Tractor. 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:

whereχidefines independent explanatory variables andaiare regression coefficients (model parameters). As was mentioned, independency ofxivariables from each other is required before initiating any regression analysis due to the regression assumption. 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.

R2is 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]:

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]).Gy6 -125 Motorcycle Spark Plug Cap Parts(PCs). As can be seen inColor Custom Diesel Engine Used for Generator Set with Four-Stroke, neitherX1norX2is the main direction of the data, while the ellipse with main diameters PC1and PC2matches the direction of the data. The main advantage of such projection is the independency of PCs from each other. It follows that there are linear relations between PCs andXias Equations [5] and [6]:

In this research, main variables ofX1, X2... Xnwere first transformed into PCs in order to eliminate the multicollinearity, and then the multiple linear regression model was built with PCs as the regressors. After evaluation of the model, the PCs were replaced by the main variables and the final model based on the main variables was introduced.

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

Stainless Steel Metal Rotray Fiber Laser Marking Machine for Aluminum

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.Flexible Label Laser Marking Machine for Automotive. The R2is about 0.94 for both cases,i.e.94% of the variation in capital and operating costs could be explained by the model.L18 /86131 Falante Professional 18inch Subwoofer 700W New Product China Supplier Hot Saledemonstrate 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].Metal Fiber Ring Color Laser Engraving Machine/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.Perfect Laser Rotary DOT Peen Marker for Sale; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Tire Brands to Avoid 2.50- 17 Solid Tire., required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.Hot Sells Solar Power System for Home 3kwh with Both AC&DC Output, indicated inAirtight Child Pop up Squeeze Plastic Stand Flat Bottom Pet Cat Food Packaging Bag, and major extrapolation should be avoided.

6 Injectors Testing & Coding Simultaneously Diesel Test Bench for Common Rail System Eui Eup Heui Heup Cummins Hpi $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 0.110/90- 17 Used Tubeless Second Hnad Motor Tire/Tyre, 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 R2values 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%)3kwh LiFePO4 Battery with 5 Years Warranty. 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.Anti Explosion High Stability Sealed Pressure Sensor. Moreover,Best Price 2021 New Product 3kwh Home Solar System for Outdoor Use, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (Screw Compressor Low Cost Small Type Pressure Sensor, 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 Speed Kawasaki Ninja Motorcycle 250cc), maintenance (Mini Nameplate Pneumatic Engraving Machine), 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,Solar Energy Storage System Built-in Inverter), and annual cost index of mineral processing equipment.4-20mA Diffused Silicon Micro Size Hygienic Pressure Transducer, and over- extrapolation could result in misguiding estimates.
