Metals from Ores: An Introduction

characteristic crystalline form. Ores are a mixture of minerals: they are processed to yield an industrial mineral or treated chemically to yield a single or several metals. Ores that are generally processed for only a single metal are those of iron, aluminium, chromium, tin, mercury, manganese, tungsten, and some ores of copper. Gold ores

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

How Hydrometallurgy and the SX/EW Process Made Copper the

In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it.

Primary Metal Production

Molten metals tend to dissolve impurities from the ore. For example, many ores that contain native copper have arsenic compounds associated with them. When the ore is melted, the molten copper dissolves the arsenic. As a result, the metal from the furnace can be less pure than the individual metal grains that were originally in the ground.
