Conda/Woodall Mountain Mine Site. Southeastern Idaho is a major phosphateproducing region, and phosphate mining has been an important industry in the area since the early 20th century. The process of mining phosphate ore resulted in open pits and piles of waste rock overburden (materials covering the phosphate ore).
For Phosphate, flotation is, in general, very important to upgrading the phosphate rock and is employed in this study to beneficiate a 20% P2O5 feed content to a 3032% P2O5 content. The growing fertilizer industry has increased the demand for phosphate rock from which superphosphates are produced. The fertilizer market is very competitive.

Three large mining machines, called draglines, excavate the remaining overburden from the mine bench down to the top of the phosphate ore and place the overburden in previously mined out areas. This process, called stripping, exposes the phosphate ore, which is then excavated by the draglines and placed on the mine bench where it is stockpiled.
The Mining Process. The mining process in Florida begins with a field study to determine the location and density of the phosphate deposits. Information like the location, size, and shape of the ore is determined to focus the mining effort. Hundreds of boreholes are drilled and thousands of core samples studied and tested to gather information ...
