Jigs & Coal Preparation
Jigs & Coal Preparation. Traditionally in coal processing jigs have been used to clean the coarse coal fraction, the +3/8″ or +¼" material. Today with the advent of modern fine coal jigs in the United States, its place was moved from the coarse to the intermediate coal circuit, the 3/8″ x 100 mesh. Recent theoretical performance and ...
Jigging
Jigging. The jig, in one form or another, continues to hold a leading place among the machines designed to separate two or more minerals of different specific gravities. It is simple in construction, easily operated, capable of treating large quantities in a short time, and highly efficient under various conditions.
Placer Gold Recovery Methods, 1986
ing. Cleaning is the re-treatment of the rough concentrate to remove impurities. This process may be as simple as washing black sands in a gold pan. Mineral concentrates may go through several stages of cleaning before a final concentrate is pro-duced. Equipment used for cleaning is often the same as that used for roughing.

Artisanal and Small-Scale Gold Mining Without Mercury
In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

Modern Methods of Dry Mineral Separation
Raw feed of coal was separated into 3 beneficiation products. Main purpose of this test was to receive clean wastes after beneficiation process. Total yield of tailings was 15.2% with calorific value around 1,311 kJ/kg, ash content 83.4% and sulfur content 0.16%. Receiving the clean coal products was not the main purpose of this test.
