Gold occurs mainly as native metal, alloyed with silver and/or other metals, and as tellurides. A naturally occurring alloy of gold and silver is known as electrum. Other gold minerals are rare. Gold is commonly associated with the sulfides of antimony, arsenic, copper, iron, and silver.3 B. Generalized Proc ess …

Flotation Tailings. Refer to P&ID 1475-P059 Flotation Tailings Sheet 1 and 1475-P060 Flotation Tailings Sheet 2. If the sand cyclone is offline, flotation tails slurry is pumped directly to the flotation tail thickener feed box and is mixed with dilute flocculant. If the sand cyclone is online, flotation tails slurry is pumped to the sand cyclone.

Recovery of gold increased gradually to its maximum value of 93.05% as the value of cyanide strength increased from 0.8 to 1.2% and the addition of sodium nitrite raise to 1.2 M. No improvement for further addition of nitrites. This introduction of new hydrometallurgical pre-treatment process has given more option for treating refractory ores.

Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical …

Hello recently, I am working on processing of a gold bearing mixed oxide-sulfide copper ore (Av. Cu; 0.80 & Av. Au; 0.2ppm). After some research and testing different methods, I found Controlled Potential Sulphidisation (CPS) Flotation as the most effective & practical method on similar ores (E.g., Kanmantoo, Australia & Kansanshi, Zambia).

The research results on floatability of old gold-bearing tailings are presented. The complex material composition and process features of processing waste are governed by difference in treatment of various ore types (sulfide, oxidized and mixed) at processing plant, as well as with supergene processes in the tailings pond. Feasibility of re-flotation of tailings is discussed. It is found …

After the gold flotation process, the tailings from gold rougher bank are pumped to the antimony flotation procedure. The antimony flotation is divided into several banks, including rougher bank, cleaner bank, and scavenger bank. The rougher bank is the first and most important step, because over 60% minerals are recovered in this bank.

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.
