preparation of gold from its ore

Use in Mining

Preparation of the ore is necessary so that it can be presented to the aqueous cyanide solution in a form that will ensure the optimal economic recovery of gold and silver. The first step in ore preparation is crushing and grinding, which reduces the particle size of the ore and liberates the se metals for recovery.

The invention relates to a method for extracting gold through potassium ferricyanide. The method is characterized in that the gold is extracted from the auriferous ores under an alkaline environment at normal temperature and pressure with nontoxic ferricyanide serving as a gold leaching agent and calcium peroxide serving as a leaching adding agent; and the method is a completely novel cyanide

Ore

Ore is natural rock or sediment that contains desirable minerals, typically metals, that can be extracted from it. Ore is extracted from the earth through mining and refined, often via smelting, to extract the valuable element or elements.. The grade of ore refers to the concentration of the desired material it contains. The value of the metal an ore contains must be weighed against the cost
