Gold extraction. This is typical of low-grade, oxide deposits. Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include grinding, concentration, roasting,

Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable.

Tailings produced from the milling of sulfide ores — primarily copper, lead, and zinc ores — may have concentrations of pyrite that are greater than those common in waste rock. Also, because tailings are composed of small mineral particles the size of fine sand and smaller, they can react with air and water more readily than waste rocks.

A metal ore may consist of any mixture (usually rock) containing a significant amount of the metal in any of its possible molecular compounds or pure elemental form. Mining will depend on the site of the ore deposit, its depth and any overburden, the required method of access to the ore deposit, and the need for handling and transport of the ore.

Employ bioleaching for base metals, such as zinc, copper and nickel, or mineral bioxoidation to enhance extraction of gold and silver. Both methods rely on bacterium, such as hiobacillus ferrooxidans, to recover precious metals. For example, stack ore in piles 200 feet deep. Apply water-diluted sulfuric acid to enable bacterium to grow.

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining.
