Dolomite is generally concentrated in the pebble fraction, typically within the size range of 1 to 20 mm. Geological and mineralogical statistics show that up to 50% of the phosphate resource would be wasted if the lower zone is bypassed in mining, and that about 13% of the phosphate resource would be wasted if the lower zone is mined but the dolomitic pebbles are discarded. Because dolomite has a lower specific gravity than phosphate, some gravity separation methods have been tested for separating the two minerals.
The current project focused on improving jigging efficiency using techniques based on gravity separation principles. Jigging is particularly attractive for this application because of the following: (1),jigs can operate with coarse feeds, thus eliminating costly grinding; (2),operating costs are much lower than flotation or heavy media separation; (3),jigs can be highly selective.
