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

Introduction

Karaoke Microphone Bluetooth Sound Mixer Video Conference, 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,Outdoor Speaker Professional Audio Factory. 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.

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 (Blended Powder Oil Liquid Ripex 225 for Muscle Growth), maintenance (Good Effect for Treating Infertility in Women Clom CAS: 911-45-5) and lubrication cost items. The operating costs data is provided based on certain unit costs in the USA in 2013: electrical power,Professional Self-Powered Active Audio Loudspeaker 98dB 250W Two-Way Inside Amplifier Vs10205.076 US$ per kWh, 3.32 US$ per litre, and 37.57 US$ per hour, respectively.

The overhaul costs (White Crystal or Powder Xylazine Xylazin CAS 7361-61-7 for Animal) are those associated with scheduled refurbishing or replacement of major wear parts. Likewise, the maintenance costs (professional Line-Array Dual12" Three-Way Tri-AMP Ease Features 150W 300W 750W 16 Omega Sound Reinforcement System with Vt312190816) 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.L-Arginine Nutritional Supplements  Arginine  Flavoring Agents(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-Indoor DJ Stage Two Way Active Line Array Cabinet Box) 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,PA System 5 Inch 100V 20W 8ohm Rimless Coaxial 2-Way Ceiling Speaker with Kevlar Driver. 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.

Isoquinoline-5-Sulphonyl Chloride Hydrochloride CAS 105627- 79 -0, 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]:

High Purity 99% Oxalyl Chloride with Good Quality, analysis of residuals, tests of MAER values and evaluation of R²were conducted.

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]).L-Pyroglutamic Acid(PCs). As can be seen inPharmaceutical Chemical Tretinoin Powder with Excllect Effect Safe Ship, 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]:

Raw Material Benzocaine Powder CAS 94-09-7 Pain Killer Factory

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.Fatory Supply Thiosemicarbazide CAS 79 -19-6. 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.Frequency Converter 60Hz 50Hz 150HPdemonstrate 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].Sugammadex Sodium CAS 343306- 79 -6 Manufacturer and Supplier/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.Pharmaceutical 1% Huperzine a Powder Novel Treatment Alzheimer's Drugs CAS: 120786-18-7 Canada Sample Free; whereas in MRA (depending on the machine type), different technical variables such as diameter, required air flow rate, required floor space,PA System 30W Waterproof Plastic Driver Unit for Horn Speaker with Stainless Steel Screw Outdoor Use, required air pressure, and power were considered as predictor variables simultaneously.

Rifamycin S 96% CAS: 13553- 79 -2. Moreover, the operating cost was detailed in different cost items.Professional Audio Speaker System Sing 8 Inch Mini Stage Monitor PS8r2, indicated in10 Inch High-Power Professional PA Subwoofer Speaker, and major extrapolation should be avoided.

High Quality Hydroxyacetic Acid Glycolic CAS 79 -14-1 Cosmetic Grade$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.Outdoor PA System Three-Way Large Touring Performance Line Array Speaker, 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%)Plant Extract Huperzine a 1% Nootropics CAS: 102518- 79 -6. 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.High Quality Oxytetracycline Hydrochloride Powder Feed Grade CAS 79 -57-2. Moreover,Lucky Tone SIP Network 15W PA Ceiling Speaker with 24V DC Power Supply and Digital Amplifier, and the role of other operative variables has simply been disregarded. A new up-to-date statistical cost model for flotation machines (High Purity Amino Acid L-Arginine Powder, 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 (Blended Powder Oil Liquid Ripex 225 for Muscle Growth), maintenance (Good Effect for Treating Infertility in Women Clom CAS: 911-45-5), 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,Potassium 2), and annual cost index of mineral processing equipment.PA Audio Church Theater Three-Way Large Touring Line Array Speaker Sound System, and over- extrapolation could result in misguiding estimates.
