Closely bound up with the practice of dry copper assaying is that of valuing a parcel of copper ore. The methods by which the valuation is made have been described by Mr. Westmoreland, and are briefly as follows :—The produce of the parcel is settled by two assayers, one acting for the buyer, the other for the seller; with the help, in case ...

The method for recovery of copper from leach solutions by precipitation with iron has been known for many years, being reported in use by Rio Tinto Mines in Spain as early as 1752. Scrap iron, detinned cans and sponge iron have been used depending on cost and availability. Labor costs involved in the use of scrap iron and cans are usually ...

By the end of 2005, proven and probable reserves totalled 112Mt grading 0.56% copper, representing a significant reduction from the tonnage and grade cited the year before. Rio Tinto recorded a $161m asset write-down in its 2005 accounts to reflect this. As of December 2013, the total proven ore reserves were 11.9Mt ore grading …

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores …
