Copper Processing Costs Analysis

Benefits and costs are generally different in nature and, to be compared, need to be converted into a comparable unit. This requires that wherever possible, benefits and costs are valued in dollars, at current day prices. The steps in undertaking a CBA are outlined as follows: Generic steps in undertaking a cost benefit analysis 1.

The costs of mining and processing copper are more closely related to the gross tonnage of the ore than the net tonnage of copper in the ore.5 A tonne of lean ore requires no more capital, energy, labor, and supplies to mine than a tonne of rich ore. However, because the rich ore con-tains more copper, it requires less of these inputs

Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity ...

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

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.
