Room and Pillar – For relatively flat ore deposits, with little change in elevation throughout, miners drill an access ramp to the deposit and remove ore in a pattern of holes (rooms) and roof supports (pillars). The rooms can be mined out using conventional chargeandblast techniques or, more commonly now, with a machine called a continuous miner.
Jul 28, 2011· The bigger your dredge is, the more material you''ll be able to process, but the more it will cost and the more it will weigh. So weight and cost are the tradeoffs for the volume you can process, and practically speaking, the depth of bedrock you will be able to reach.

Flotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine.

Heating ores to elevated temperatures is called roasting, and it causes the oxygen in the air to convert the sulfur in the ore to sulfur dioxide, which is a gas and is emitted to the air. The process works best when the ore is crushed to small pieces before roasting.
Generally, if you want to make a nice quiet power sluice or recirculator, a 12 volt electric pump is recommended. These pumps are submerged and make no noise. If you prefer a high banker with high pressure spray bars, you are going to need a gaspowered pump. Keep in mind that a pump delivers less water as your equipment location is moved uphill.

In the early 1940''s Humphreys Mining Company in Florida pioneered heavy mineral raining with a dredge in the United States. In 1948 Du Pont, in conjunction with Humphreys, opened their first of two mining operations recovering a titanium dioxide product in Florida. Later on in 1952 Du Pont opened their second plant, both of which used a cutterhead suction type of operation. This process is ...
