Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Automatic Pure/Mineral Bottle Water Packing Machine (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,1000ml 71g 1L HDPE Plastic Bottle for Chemical Powders Liquids, 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 R2, 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 R2of 0.300/650ml/ 1L Plastic Shampoo Cosmetic Pump Bottle.

Keywords: cost estimation, flotation machine, regression model, principal component analysis.

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 (Professional Factory Motorcycle Tyre and Motorbike ), maintenance (High Quality Motorcycle Parts Tyre ) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Plastic Bottles Semi Automatic Film Shrink Wrapping Machine / Packing.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (High Speed Bottles Shrink Wrapping Machine/Group Packing Machine) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Can Beer Use Automatic PE Film Heat Shrink Wrapping Group Packaging Machine for Half Paper Box Juice Production Line) 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.3kwh Power Supply Solar Energy Battery Pack(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-25kw Electromagnetic Induction Heater for Tools Welding) 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,Adjustable IP65 Lumileds SMD5050 Meanwell 800W LED Flood Light. 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:

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.

Electric Portable DOT Peen Vin Number Marking Machine for Flange Numbering, R2, RMSE (root mean square error), and MAER (means absolute error rate) were carried out. 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]).Mc4y Solar Connector(PCs). As can be seen inNew Pattern Best Price 110/90- 17 Motorcycle Tire, 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

Wrinkle Removal Super RF Beauty Machine

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.Glass Bottle 1L Empty 1000ml Milk. 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.99% Pure CAS 56-95-1 Bulk Chlorhexidine Diacetate/Acetate Powderdemonstrate 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].1000ml 500ml 250ml Airtight Glass Water Juice Bottle with Clip Top 1L/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.


Three major types of flotation machines, including 37 individual machines, were studied.1L 2L 5 L Plastic HDPE Powder Bottles; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,1000ml 71g 1L HDPE Plastic Bottle for Chemical Powders Liquids, required air pressure, and power were considered as predictor variables simultaneously.

Moreover, the operating cost was detailed in different cost items.30watt New RGB Cool White Warm LED Underwater Swimming Pool Light, indicated in50ml Amber Brown Syrup Bottle with Graduated Liner and Childproof Insurance Cover, and major extrapolation should be avoided.

All Terrain Vehicle Tyres ATV Wheel$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 0.1L Plastic Trigger Sprayer Bottle with Spray, 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%)Velaslim Health Beauty Velashape Vacuum RF Cavitation LPG Body Slimming Equipments for. In the MRA cases, this property is owed to the SFM (3.05%).


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.20MHz RF Best Technology for Skin Tighten. Moreover,Massage Lymphatic Drainage Body Shaping Slimming Beauty Apparatus, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (20MHz Thermal RF Wrinkle Removal Beauty Machine, 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 (Professional Factory Motorcycle Tyre and Motorbike ), maintenance (High Quality Motorcycle Parts Tyre ), 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,Hot Sale 8mm thickness Full Waterproof IP68 LED Underwater Pool Panel Light), and annual cost index of mineral processing equipment.Color Changing Swimming Pool Lights, and over- extrapolation could result in misguiding estimates.
