Au–Cu alloys containing base metals can be processed in oxidized sulfate medium, as shown by the generalized flowsheet in Figure 47.2 (Subramanian et al., 1980). Particle size is most important for effective dissolution and is achieved by melting the alloy and water atomizing at pressures of 1000–5000 psig.
In the electrolysis of alumina, cryolite is added to
The fusion temperature of pure alumina is about 2000 ∘ C and at this temperature when electrolysis is carried out on the fused mass, the metal formed vaporizes, as the boiling point of aluminium is 1800 ∘ C. These difficulties are overcome by using a mixture containing alumina, cryolite (N a 3 , A l F 6 ), and fluorspar (C a F 2 ,). But the

Fluorite Wikipedia
The first official recognition of fluorspar in the area was recorded by geologist J.B. Jukes in 1843. He noted an occurrence of "galena" or lead ore and fluoride of lime on the west side of St. Lawrence harbour. It is recorded that interest in the commercial mining of fluorspar began in 1928 with the first ore being extracted in 1933.
