gold ore sorting gold - birdsandbots.nl

· A gold sorting plant in which the gold content of lumps of ore is measured by means of a neutron activation analytical technique. Separate lumps of gold ore are graded in two sizes which are presented to an irradiator such as to irradiate them uniformly.

Ore Sorting & Pre-Concentration

The available sensor technologies for particle ore sorting are not able to directly detect gold occurring at the typical fine grain size of most deposits, be they refractory or free milling. Therefore, the sensors are used to detect minerals associated with gold or alternatively characteristics of gangue or waste material.

How to Separate Gold from Pyrite

In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton. This ore yielded only about 40 per cent, on being amalgamated, but over 90 per cent, was dissolved out by leaching the raw ore with cyanide of potassium, and similar results were obtained by chlorination.
