How to prospecting for gold

Grinding process



There are three methods used to separate gold from raw materials or sea water, namely: buoyancy, and cyanide, carbon and pulp.



Buoyancy. Excreted in the flotation process (the process of flotation) of raw ground fine particles from each other, based on the ability of different metals in the raw associate themselves with the foam painting. Mix oils and chemicals called factors buoyancy water before mixing the raw powder, and used three types of chemicals: the foam agent and a factor mosque and a variety of inorganic chemicals. Working cause foam puffs in water, and the Group of the Whole is a layer of gold to make it stick to air bubbles that float on the surface, the inorganic chemicals are prevented other metals to form that class which has acquired the gold. After the development of raw water, air enters into the solution, This process is called ventilation, and thus bear the gold particles to the top and Takect class foam.



Method of cyanide. Contains a process to develop a raw powder in the tank contains a dilute solution of cyanide, and then separating the gold in solution or deposited metal zinc.


The method was used for the first time in South Africa in the nineties of the nineteenth century, a very effective method extracted 90% of gold with crude, and using this method can extract gold from piles of waste material extracted from gold mines.




Pulp carbon. Which is another way you need to use cyanide. And where is first mixed raw powder with water to get to the door, and then melted the content of gold in cyanide solution. The carbon particles are added to his door to collect the gold ions (electrically charged atoms) on the surface. And then still Allababp of carbon particles, particles are then placed in a solution of cyanide alkaline (caustic) Hot, which in turn separates the gold from the carbon.
