  • Ql CO Procedure - Metallurgist & Mineral Processing Engineer

    Fire assaying is an ancient form of quantitative chemical analysis by which metals are separated and determined in ores and metallurgi­ cal products with the aid of heat and dry reagents. At present, this technique is used principally to preconcentrate the noble metals from ores or metallurgical products. The object is to form a melt of at least
