Galena Jigging - Metallurgist & Mineral …

Your galena would need to be the sole mineral in your 'ore' I think. You likely can only answer all those questions be laboratory testing. Do you need to recovery your galena coarse to use it instead of ferrosilicon in a heavy media separation (sink/float) plant? If your galena is coarse grained, it will still jump out of a flotation cell.

how to separate galena and calcite

Mineral Identification Key Cleavage. Calcite is another good example, breaking along three different planes that yield blocky fragments that look like a rectangular box that has been warped – called a "rhombohedron" or, simply, "rhomb." Galena breaks along three planes at right angles to one another, producing true cubes as fragments.

Lake Galena (Pennsylvania) - Wikipedia

History and Hydrology. Lake Galena in its current form was created when the county flooded the lake in 1972.Before that time, much of the lakebed had been part of the village of New Galena, the economy of which was based largely on farming. Mining of galena (in addition to small amounts of zinc, silver, copper and gold) had been mildly successful since the property was purchased in 1861.
