Electrochemical leaching method of gold from sulphide ores. Patent No. 4186 UZ

The invention relates to hydrometallurgy and methods of electrochemical chloride leaching of gold from sulphide ores and sulphide bearing minerals.

Task: Development of method of electrochemical leaching of gold from sulphide ores which enables to simplify the process and increase productivity.

Essence of invention

Weakness of this method: when volume current density reaches 20 A/l, the leaching process sharply slows down, and pH rises up to 9.

The technology is covered by patent No. 4186 UZ. Know-how is available.

The technology may be transferred under license agreement. Please send your offers for acquisition of license to the following address: 27 Navoi Str., Navoi 210100, Uzbekistan.
