· Copper can be drawn into thin wires. How many meters of 34-gauge wire (diameter = 6.304 x 10^-3 in) can be produced from the copper in 5.01 lb of covellite, an ore of copper that is 66% copper by mass? (Hint: Treat the wire as a cylinder. d of copper = 8.95 g/cm^3) So I used the formula …

cline in ore grades, so production costs have fallen over the long term. Byproducts Copper is usually not the only product of cop-per mines.7 Often molybdenum, lead, zinc, gold, or silver, and sometimes nickel or cobalt are also extracted from copper ore. These min-erals can be either byproducts or co-products.

A copper concentrator is milling 15,000 tons/day of a chalcopyrite ore assaying 1.15% copper. The concentrate and tailings produced average 32.7% and 0.18% copper, respectively. I let you do the math! Three product (bi-metallic) formulas

Hence the calculation is: OEE = (Good Count × Ideal Cycle Time) / Planned Production Time. Although this is an entirely valid calculation of OEE, it does not provide information about the three loss-related factors: Availability, Performance, and Quality. For that – we use the preferred calculation.

These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral.

Note: When the cost price per tonne can not be found in the mining company's feasibility study, I kindly ask the mining company's management to give me their best estimate. In order to be extra conservative in my calculation, I normally apply a discount rate of 20% on the numbers received.

Using equivalent grade factors to find the optimum cut-off grades of multiple metal deposits. ... (NSR). NSR represented the total value of metals recovered from each ton of ore minus the cost of smelting (Annels, 1991). ... is the fundamental formula for calculation of optimum cut-off grades of ore.

Simply put, cost per tonne is the total cost of your logging operation divided by your total production. The concept is easily represented as a mathematical equation: Cost per tonne = Total Cost ($) / Total Production (tonne) Unfortunately the process leading up to plugging numbers into this simple formula can be complex and daunting.

· An excess of sodium hydroxide was added that caused the copper to precipitate as copper hydroxide (Cu(OH)2). The copper hydroxide precipitate was filtered then briefly washed with cold water to remove any soluble salts, then thoroughly dried to give a constant mass of 2.31g. Calculate the percentage mass of copper in the copper ore sample.

About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it …

Ore operating cost reflects multiple concentrating stages whose unit costs are measured in different denominations, such as: process costs per tonne of mill feed, mining costs per tonne of ore, transport costs per tonne of concentrate and refinery costs per kg of product.

geology of copper–the kinds of copper minerals, how they formed, and where they are found. The chapter then discusses current world copper re-sources, and the copper content (or ore grade) of current mine production. The relations be-tween ore grades, tonnages, and production costs are discussed in chapter 9. I Brian j.

freight costs contribute considerably to the purchase price of iron ore for the steel plants (iron ore is a low-value bulk product), this is not true for tungsten concentrates which are a high-value product. For initial rough estimates the freight aspect can in such cases be neglected. Calculation of the Net Smelter Return (NSR) of a Mine

where R represents the ratio: % Pb in crude ore/% Cu in crude ore Formula (32) is very convenient for milling calculations on ores of this type. Example: An ore contains 5% lead and 1% copper. The ratio of perfect concentration for a concentrate of maximum grade and recoveries of lead and copper …

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. Do You Want to ...

Copper and Aluminum Price Calculation : The material price for cables and wires is usually based on a copper price of 150.00 EUR/100 kg. For invoicing, as copper surcharge – the difference to the daily copper rate will be calculated. Formula for calculating the copper surcharge:

The element copper has the chemical formula or symbol Cu. This chemical symbol originates from the Latin word "cuprum," which means "of the Cyprus island." The atomic number for copper is 29, and it is a member of group 11 on the periodic table.
