THE IMPORTANCE OF DILUTION FACTOR FOR OPEN PIT …

grade means lower mill recovery. Dilution also increases the cut-off grade which in turn reduces the overall ore utilization of a mine. In some cases, to take advantage of economies of scale, mining operations tend to plan for higher mining rates. Moving to a larger scale of operation means less selectivity, hence more dilution.

Potash - Wikipedia

Potash (especially potassium carbonate) has been used in bleaching textiles, making glass, and making soap, since about AD 500.Potash was principally obtained by leaching the ashes of land and sea plants. Beginning in the 14th century potash was mined in Ethiopia.One of the world's largest deposits, 140 to 150 million tons, is located in the Tigray's Dallol area.
