Copper-Zinc ores - Danafloat

The copper flotation tailings are the feed to the sphalerite flotation circuit where the zinc minerals are floated as explained in the lead-zinc flotation section. Sphalerite is first activated with CuSO4 and floated typically at elevated pH for iron sulphide depression. Combinations of xanthate with either dithiophosphate and/or thionocarbamate are used in combination with

Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation

14.04.2016  The Problem with separating Copper from Zinc by flotation. The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present. This is usually the case in ore deposits near the surface or in tropical countries where the annual rainfall is quite high. The method of ore

Copper-Lead-Zinc ores - Danafloat

Copper-Lead-Zinc ores The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage.

Copper Lead Zinc Ore Flotation Plant - Pineer Mining Machinery

Copper Flotation is a beneficiation method based on the hydrophobicity difference of the mineral surface. While the copper mineral is usually in the form of sulfuration exiting in the mineral. Its natural floatability is good, so froth flotation is the main method of extracting copper ore. According to the processing order of the useful mineral, the copper ore processing/mining can

Cu-Pb-Zn, Copper-Lead-Zinc Ores, Copper Lead Zinc Flotation

It is reported that more than 90% of non-ferrous metal ores (copper, lead, zinc, etc.) adopt flotation process, especially for those with fine grain and complex symbiosis. Flotation process can achieve ideal separation effect, and separately recover low-grade ore then enrich multiple high-grade concentrates. Different ore properties means different flotation process.

Method of flotation of sulfide copper-zinc ores

Copper-zinc ore is enriched by the scheme of direct selective copper flotation. The ore is ground with the addition of calcium oxide to create an alkaline environment and depression of pyrite, sodium sulphide and zinc sulphate for depression zinc materials. The crushed pulp is subjected to conditioning with reagents-regulators sulfur NAT is ...

Lead-Zinc ores - Danafloat

Flotation separation and recovery of lead and zinc concentrates from ores containing galena (PbS) and sphalerite (ZnS) is well established and generally achieved quite effectively. Silver often provides highly significant economic value, if not the greatest value, with the silver most often associated with the galena mineralization which is fortuitous since smelters pay more for

Froth Flotation Process - Mineral Processing Metallurgy

20.01.2021  Although the flotation of the commoner ores, notably those containing copper and lead-zinc minerals, has become standardized to some extent, there is nevertheless considerable variation in the amount and nature of the reagents required for their treatment. For this reason the running costs of the flotation section of a plant are somewhat difficult to predict accurately
