Processing Methods. Although there are a number of different diamond recovery technologies being utilized worldwide, the two principal types are Rotary Pan plants and Dense Media Separation (DMS). Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery.

The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.

Mineral sands are mined by surface mining methods including open cut mining, suction dredging and hydraulic mining. ... Using electrostatic separation techniques the conductors (rutile and ilmenite) are separated from the non-conductors (zircon and monazite). Magnetic separation is used to separate the magnetic minerals (ilmenite and monazite ...
Mining methods Mining techniques have dramatically transformed over many years, with technological advances improving efficiency and the safety and health of our people, while minimising the environmental impact of our operations. NSW has both open-cut and underground mines.
Mining in hard and soft rock formations require different techniques. Other methods include shrinkage stope mining, which is mining upward, creating a sloping underground room, long wall mining, which is grinding a long ore surface underground, and room and pillar mining, which is removing ore from rooms while leaving pillars in place to ...
Data is increasing daily on an enormous scale. But all data collected or gathered is not useful. Meaningful data must be separated from noisy data (meaningless data). This process of separation is done by data mining. There are many methods used for Data Mining but the crucial step is to select the ...
Separating fine gold particles from black sands is one of the biggest challenges that gold prospectors have to deal with. This article will describe a simple and inexpensive method of capturing fine gold. Most small scale prospectors do not need to invest thousands of dollars to capture small placer gold dust. Using fine gold recovery methods, you can retain the vast majority of gold in your ...
