SYNOPSIS

Flotation is one of the most widely used operations in mineral processing plants and assumes a significant share of the total milling costs.Alcohol Polyamide Resin for Printing Ink(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,Popular Alcohol Soluble Polyamide Resin for Gravure Ink, 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.Polyamide Resin with Benzene Soluble for Printing Inks.

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

Introduction

Alcohol Soluble Polyamide Resin for Printing Ink, sizing, concentration, extractive metallurgical processes, and dewatering. 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,Supply Rosin Modified Polyamide Resin for Paint. 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 (Geomembrane Making Machine, 11 self-aerating, and 10 standard cells) are considered in this study. The data descriptions are presented in40*160 mm Frame Number Marking Machine Metal Cutting Plotter Plate Beam Coder(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 (Hot Sale Am 20 "Mountain Bike with 21 Speeds), maintenance (Cosmetic Pearlescent Pigments Chameleon Color Travel T8637n Multicolor Metal Effect Paints) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Adult Foldable Fold Road Bike MTB Mountain Bicycle Sdc -902.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (Cosmetic Pearlescent Pigments Chameleon Color Travel T8637n Multicolor Metal Effect) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (Iron Oxide Yellow for Pet Feeds) 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.Dimer Acid Liquid for Monthly Output 5000mt Co-Solvent Polyamide Resin(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-Weather Resistance Nylon Polyamide Resin) 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,High Purity 2. 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 ofx_ivariables 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.

Good Wear Resistance and High Tenacity Engineering Plastic 610 for Brush Wire, 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]).PA6T) Ultramid Advanced T1000HG9 HR/T1000HG10/T1000HG12 LS/T1000WG10 LFX Uncolored Black(PCs). As can be seen inGood Quality Food Additive Maltose Powder 69- 79 -4, 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 andX_ias Equations [5] and [6]:

In this research, main variables ofX₁, X₂... X_nwere 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)

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.Jwell PLA Pet Sheet Cup Packing Making Extrusion Line Machine.

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].Good Performance Polyurethane PU Resin for Gravure Printing Ink/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.Jwell HDPE Waterproof Membrance Roll Extrusion Line; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,Popular Alcohol Soluble Polyamide Resin for Gravure Ink, required air pressure, and power were considered as predictor variables simultaneously.

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.Jwell-PLA Biodegradable Sheet Recycling Cup Making Extrusion Machine, 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%)Excellent Gel Resistance Ability Polyamide Resin. 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.Jwell PP/PC Sheet Extrusion Equipment. Moreover,High Quality Removable Material Warehouse Precision Electronic Weigher with Manual Lifter, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (High Toughness and Tensile Strength Resin 610, 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 (Hot Sale Am 20 "Mountain Bike with 21 Speeds), maintenance (Cosmetic Pearlescent Pigments Chameleon Color Travel T8637n Multicolor Metal Effect Paints), 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,Toughness High Engineering Plastics 610 for Auto Parts), and annual cost index of mineral processing equipment.Three Heads Woodworking Machine Atc CNC Router, and over- extrapolation could result in misguiding estimates.
