17 Flotation of Gold Ores Aalto

The flotation of gold-bearing ores is classified according to ore type (i.e. gold ore, gold copper ore, gold antimony ores, etc.), because the flotation methods used for the recovery of gold from different ores is vastly different. 17.2 GEOLOGY AND GENERAL MINERALOGY OF GOLD-BEARING ORES

Flotation of Gold and Gold-Bearing Ores ScienceDirect

Jan 01, 2016· Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold

Gold-Copper Ores ScienceDirect

Jan 01, 2016· Today, flotation is commonly used in the processing of primary copper–gold ores to produce a copper concentrate containing gold as a co-product, where the gold is recovered as a byproduct of copper smelting and refining (La Brooy, 1992). The gold is usually discrete and either free, associated with copper sulfides or associated with iron

Aug 01, 2000· 1. INTRODUCTION Gold-Copper ores, which require a Dllrumum of two metallurgical processes such as the production of a copper concentrate as a by-product to recover the copper content of the ore, and, the subsequent cyanide leaching of the flotation residues to recover the remaining associated gold, present, in most cases, processing challenges.

Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an

ore prior to flotation. This means that 70% of the total ore reports to flotation at the designed head grades. Higher magnetic content of the ore has two implications: Capacity of the magnetic circuit must be increased Fewer tons of ore will report to flotation which can have both positive and negative effects.

Improving the recovery of gold and copper in a CIP

The plant was experiencing problems in the leach, adsorption, elution and electrowinning sections mainly as a result of the presence of copper in the ore. The changes made to the operating standards, the response of the circuit to these changes and the final Circuit layout and operating conditioning resulting in a 90% gold recovery are discussed.
