Experimental results demonstrated the suitability of gravity beneficiation procedures for the preconcentration of gold particles in the sink and the elimination of much of the contaminants: it was possible to obtain a theoretical recovery up to 90% for gold particles bigger than 35 μm. Practical application on the real handwashing sample has led to a maximum recovery of up to 68%.Cited by: 8

Apr 15, 2019 · The loss of precious metals such as gold&silver in the production process affect the cost parameter significantly. The recovery of scraps and wastes in gold jewelry manufacture is a critical subject for an economic jewelry manufacturing. The contents can be high to medium grade in terms of precious metal content (Corti, 2002, Hoke, 1982). Similar to scraps, jewelry wastes are produced at …Cited by: 6

The recovery of precious metals can be successfully managed from waste which is considered to be secondary sources of raw material. Waste derived from jewelry activity falls in this category, and represents an essential component of precious metals. The most important metals in the jewelry sector are gold (Au) and silver (Ag).
