Flotation of phosphate ores containing dolomite . Sulfonated linear fatty acids have been used before in the phosphate chemical industry, but they have been used only as deing agents, not as an anionic flotation agent for floating alkaline earth metal carbonate impurities such as dolomite away from apatites such as francolite, carbonate fluorapatite and other phosphatecontaining ores such

· There is a difference between floating crushed ore with minimal exposure of gold and floating free gold with 100 percent exposure. No, you can't float nuggets but everyone has seen fine gold float in a pan. Add a drop of Pinesol and you will see gold float. Detergent "suppresses" flotation. It is referred to as a suppressant.

Set the gold ore and a small quantity of lead in a cupel. Place the cupel in a blast furnace. Heat the mixture until the lead and gold ore liquefy. The blast furnace batters the cupel with hot air. The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore.
