Extracting gold can be done through amalgamation, gravity concentration or leaching. Historically, mines would use amalgamation (with mercury), but technological advances have now replaced this process. These processes are more efficient and require less regulation for worker safety. ... For example, some mills used a ball mill, while others ...

Ball mill is a piece of important grinding equipment, which is widely used in mineral processing, building materials, and the chemical industry. It can be used for dry or wet grinding of various ores and grindable materials.

As an alternative, field tests were conducted in Portovelo–Zaruma, Ecuador. As Ecuadorian artisanal miners perform whole ore amalgamation in ball mills, the results of this investigation are easily applicable to other sites with similar characteristics, such as Talawaan, Indonesia or Northeast Antioquia, Colombia.

The pan amalgamation process is a method to extract silver from ore, using salt and copper(II) sulfate in addition to mercury.The process was widely used from 1609 through the 19th century; it is no longer used. The patio process had been used to extract silver from ore since its invention in 1557. One drawback of the patio process was the long treatment time, usually weeks.

A ball mill has a cylindrical rotating mixing vessel, which is partly filled with round balls. These balls must have a larger diameter than the product that is to be grinded. The material of these balls depends on the type of product. The size of the bullets depends on the desired application. Larger balls grind or cut the product and finer ...

including the local methods used for amalgamation, will briefly be described. 2.2.1 Amalgamation The ore is crushed and milled together with water in tumbling mills, so called ball mills, where the balls have been replaced by iron rods in an iron drum (about 2 m60.5 m), and rotated by an electrical motor (2.5–3 Hp per drum).

Jigging ~ A jig is a machine that uses a stream of water to separate gold and sulfides from most of the sand made by the ball mill. The gold, sulfide (because it is also heavy), and a little sand settle into the hutch of the jig and this mixture is called the "jig concentrate." It now must be subjected to the amalgamation process.

Also in the the ball mill directly amalgamation job instance, but the Since amalgamation in ball mill recovery rate is low, the loss of mercury, larger issues such as health hazards to the environment and workers now have less use, only some of the backward areas also to use Nianpan machine or a ball mill directly amalgamator.
