filtered, and then dried to form a powder (copper concentrate). This process is usually able to recover 85 to 95 percent of the copper in the ore. The dried concentrate contains approximately 20 -30 percent copper by mass, 30 per cent iron, 30 per cent sulphur, with the remainder including

For example if a certain ore type has an on-site processing cost of $20/tonne and G&A cost of $5/tonne, then in order to breakeven the ore NSR block value must exceed $25/tonne. If one decides to include mining costs and sustaining capital costs, then the NSR cutoff value would be higher.

Use the scrap copper melt value calculator to find how much your items are worth in copper content, or in determining what you might be willing to pay based on the spot price of copper. The copper scrap calculator will show you the price for 100% pure copper, unless you indicate a lower percentage.

This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from 100%: % Cu Loss = 100 - 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.

What is the formula for copper ores?

copper produced in the United States originated from flotation (Daniel E. Edelstein, Copper Commodity Specialist, U.S. Geological Survey, written commun., March 20, ). Copper sulfide ores must be concentrated before they can be economically transported to a smelter.

Transformer Life-Cycle Cost (Total Owning Cost) This article is excerpted from "Premium-Efficiency Motors and Transformers", a CD-ROM is available from the Publications List. Introduction. Transformers typically can be expected to operate 20-30 years or more, so buying a unit based only on its initial cost is uneconomical and foolish.

Aug 24, · 4. 200 yuan in part b refers to port charges including clearance costs, warehouse fees, etc. 5. We use LME 3M copper at 15:00 Beijing time. 6. We also include the Chinese import tax for the metals in the calculation. For copper and aluminium there is no import tax, but there is 1% tax for zinc and 2% tax for nickel.

In the case of multiple processing options, cut-off grade is used to determine which process or destination the ore will be sent to, by using the following equation: Where U1 is the utility of sending ore to process 1, and U2 is the utility of sending ore to process 2. Utility is defined as the value (economic or otherwise) of selecting a process.

Copper concentrates are produced by the beneficiation, or upgrading, of copper ore. A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters.

About Copper; Copper weighs 8.94 gram per cubic centimeter or 8 940 kilogram per cubic meter, i.e. density of copper is equal to 8 940 kg/m³; at 20°C (68°F or 293.15K) at standard atmospheric pressure.In Imperial or US customary measurement system, the density is equal to 558.106 pound per cubic foot [lb/ft³], or 5.168 ounce per cubic inch [oz/inch³] .

Determine the BESR in mining and processing a 0.60% copper ore deposit if the selling price of copper in concentrate is $1.63/kg and the overall unit costs are $6.80/ton and the cost of handling unit weigh of waste is $7.50/ton. The overall recovery is 92%.

Price Calculation Formula. 70% of the Price of prime quality copper traded at LME . Copper-Ore (Copper – Cu) Minimum 10% to Maximum 15% (Mixed) ¨ Cost

The flotation cost incurred is 9% of the capital raised, and the growth rate is expected to be 7%. NPV = [ ($4,500,000 / 1.1146) + ($4,500,000 / 1.1146 2) + ($4,500,000 / 1.1146 3 )] – ($10,000,000) = $909,300.

Oct 27, · This specific heat calculator is a tool that determines the heat capacity of a heated or a cooled sample. Specific heat is the amount of thermal energy you need to supply to a sample weighing 1 kg to increase its temperature by 1 K. Read on to learn how to apply the heat capacity formula correctly to obtain a valid result.

Only where a group of mines operates in a single district are costs comparable and then only with reservations. In general, cost systems are fairly uniform, yet in studying costs of a number of plants it is noticeable that in some cases there is a tendency to omit certain operations which are proper charges against ore dressing and treatment. These should cover the first stage of coarse

mill capacities. These costs were estimated from inhouse historical data for a variety of plant capacities, as illustrated below. These estimates were based on a hypothetical mine with the key assumptions, as outlined below in Table 3. Capital and Operating Cost Estimates for Copper Mine and Mill 0 200 400 600 800 1000 1200 1400

Calculated Results: Results are calculated using the following formula: MetalEq (percent) = G pri + (G pri × [∑ i R i S i V i G i]/(R pri S pri V pri G pri)) where R is the respective metallurgical metal recovery rate, S is the respective smelter return rate, V is metal price/tonne, and G is the metal commodity grade for the suite of potentially recoverable commodities (i) relative to the

The average grade of copper ores in the 21st century is below 0.6 percent copper, with the proportion of ore minerals being less than 2 percent of the total volume of the ore rock.

6/23/  · Effective costs of Copper Processing Example of porphyry copper mine processing costs Assuming a freight cost of £ 20/ton of concentrate, The total deduction are £ (0.61 + 0.56 + 0.41) = £ 1.58 The NSR per tonne of ore treated is thus As mining, milling, and other costs must be deducted from thisfigure, it is apparent that this mine with

The following table uses live Grand Exchange Market Watch prices to calculate the profit or loss from smelting ores. Ring of forging decreases the amount of iron ore needed by 1, at the cost of 1 charge per use. At a certain level, each bar has a 10% chance of smelting double bars.

Copper Quotation averaged over the quotational period. Example) For a concentrate with a copper content of 30 % the payable copper value is: 30% x 96.65% x 7,000 USD/t-Cu = 2,030 USD/DMT Example) For a concentrate with a copper content of 24% the payable copper value is 24% – 1%-unit = 23% i.e. 23/24 x 100 = 95.83% payment:

How to calculate: Calculation Formula for all metals mentioned above = (International Price) x (USD to INR rate conversion) / (Metric Ton to Kilogram Conversion) INR Aluminum: (2132 x 45.8702) / 1000 = (97795)/1000 = 97.795 INR
