Gold Assaying Methods

 · To determine the amount of gold metal in ore, there are two kinds of gold assay adopted:. The dry assaying method (i.e. by fusing the powdered ore with or without fluxes).; The wet assaying method (i.e. by the agency of liquids).; In the principal wet assay, the ore is thoroughly dissolved in acids, and, by the addition of reagents, precipitates containing the metals are thrown down.

Gold processing

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied.

Ore

Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.

Gold grade

The term gold grade is commonly confused with gold purity, with the two meaning something quite different. Gold grade is a term used in gold mining, and should be used as a measure of the quality of gold ore – that is the raw material obtained from mining. Gold purity measures the amount of yellow gold mixed with other metals in finished gold products or, more strictly, gold alloy products.

gold ores can be classified into 11 types (Table 1). Some metallurgical implications to these gold ore types are summarised below: Placers, quartz vein gold ores and oxidized ores: Generally, placers, quartz vein gold ores and oxidized ores are free-milling and gold can be recovered by gravity and/or direct cyanide leaching.
