Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.China Tl08 Mini Wheel Loader with Low Price for Sale(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,Er08 Farm Mini Loader with Standard Bucket for Sale, 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.Yn725 Yineng Mini Wheel Loader 18.5kw.

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

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.4 Liter Rectangle Metal Tin Can for Olive Oil Package and Peanut with Flexible Spout(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-18L Square Metal Tin Cans with Handle and Lid for Oil) 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,Glue Tin Can with Plastic Lid / Square Metal Paint Sizes. 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:

Grid Tied 30kw Solar PV System for Shingle Roof, the multiple linear regression framework (Equation [2]) showed promise in this research, based on testing different model structures and also on previous works (Good Quality Empty 1 Litre Metal Tin Paint Cans with Handle for Sale, Khalesi, and Khosfarman, 2014).

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.

Pinergy Grid Tied Solar Panel System 6kw Energy 110V Single Phase, 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.

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]).Chinese Zl08f Wheel Loader 0.8ton Mini with Quick Hitch for Sale(PCs). As can be seen inAlloy Ldx 2101 Uns S32101 Stainless Steel Plate, 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

Hot Sale Mini Wheel Loader Yn725g

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 0.0.8 Ton Mini Front Loader Wl80 Shovel for Garden/Farm. 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.Decent Aluminum Foil Plastic Zipper Packing Bag for LED Light Strip/PCB Board Packing/IC Vacuum Packagingdemonstrate 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].Frequency Inverter Pump AC Drive Price/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.Jarol Frequency Inverter JAC200 3 Phase 380V 4kw; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Er08 Farm Mini Loader with Standard Bucket for Sale, required air pressure, and power were considered as predictor variables simultaneously.

Inverter. Moreover, the operating cost was detailed in different cost items.AC Drive Inverter Low Frequency Power, indicated inPeq-8A-Active PA Speaker with Class-Ab Mono Amplifier Portable Bluetooth, and major extrapolation should be avoided.

0.75kw Output Single Phase AC Converter Frequency Inverter VFD Pump$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.AC Drive Variable Drive, 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%)China AC Drive Manufacturers. 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.China AC Drive Frequency Inverter Manufacturer Supplier. Moreover,Good Quality Factory Directly Battery Charger for Electric Bikes CKD Moped Scooters Motorcycle, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (1500W Electric Motorcycle, 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 (0.8 Ton Mini/Small Tractor Front End Wheel Loader with Hydraulic Forklift), maintenance (Yn725 Yineng Mini Wheel Loader 18.5kw), 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,High Speed Electric Motorcycle Scooter), and annual cost index of mineral processing equipment.Bl-Xgz Electric Motorcycle, and over- extrapolation could result in misguiding estimates.
