Line processing of gold and silver flotation concentrates. C22B3/02 Apparatus therefor. C22B11/08 by cyaniding. The invention relates to the metallurgy of noble metals, in particular to the hydrometallurgy of gold and silver. The invention improves the extraction of gold and silver from flotation concentrates respectively to 95.5% and 65%.
A total recovery of more than 97% of the gold and silver is made by flotation, while the combined flotation cyanidation process gives an overall extraction of 95%. The installation is much more compact and its capital cost far less than one embodying fine grinding and cyaniding of the whole tonnage, and it can be run with lower operating ...
The flotation amp; cyaniding method is the most important process among the whole, silver concentrate can be got in the process of flotation, then regrinding to the next process including cyaniding and leaching, countercurrent washing, zinc powder replacement, silver ingot can be finally got after electrolytic dissociation.
GOLD FLOTATION. The flotation process, which is today so extensively used for the concentration of base metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.
Depending on the unique characteristics of your ore, Nalco Water offers a comprehensive suite of gold and silver processing solutions that apply to leaching, milling, roasting, and flotation. By choosing the appropriate partner, you can significantly improve the recovery and grade of your product while maintaining productive performance and ...
Silver ethyl xanthate is the species formed on pure silver above 30 mV and on a goldsilver alloy of equal gold and silver content at around +20 mV. From this, it is obvious that the flotation of goldsilver alloys can be achieved at potentials considerably lower than those for gold.
