Copper Flotation Plant in Pakistan | CNFREE

11.06.2020· The copper flotation plant in Pakistan has a processing capacity of 1500tpd. The raw ore was characterized by simple composition. It consisted of metallic minerals (copper pyrite and pyrite) and non-metallic minerals (quartz and chlorite). The multi-element analysis results showed that Cu was the valuable element. The Cu grade of the raw ore was 0.80%.

NICKEL AND COBALT ORES: FLOTATION

A typical example of a nickel sulRde plant operat-ing with highly Soatable talcose gangue is at Trojan mineinZimbabwe.TheZimbabweansulRdedeposits contain very low grades of nickel (0.6%) and copper (0.04}0.4%). The easily Soatable non-sulRde min-erals dilute the grade of the concentrate and also result in nickel losses into the tailings. This problem

There are more than 45 different nickel minerals, but only a few are of economic importance. Table 16.1 lists some of the most important nickel minerals. Nickel, in various ores can also be found in other minerals, such as pyrrhotite and various cobalt minerals as an exsolution in isomorphic phases. Nickel minerals can be divided into three major groups, including nickel sulfides, nickel arsenides and nickel antimonides, normally the minerals of magmatic and hydrothermal origin, nickel ...

In the flotation process, a number of reagents are seen as a means ofdepressing pyrrhotite. However, the complex surface chemistry of the nickel-copper ores appears to challenge the effectiveness and consistency of these reagents; in many cases, testing indicates that pyrrhotite continues to float when it is not supposed to. Some ofthe contradictory results may be attributed

Copper-Nickel ores - Danafloat

Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the pH up to 12 with lime and a small amount of sodium cyanide. Elevating the slurry temperature to 30-35 degrees C …

Historically, selective flotation of copper from nickel sulfides has been achieved through pH modification; however, this method is rarely efficient, resulting in significant rejection of copper units to the nickel circuit. In Strategic Metallurgy’s experience, this alternative method is robust, easy to control and results in improved grade recovery profiles. This method has been trialled …

Sequential Selective Flotation Process Flowsheet

08.03.2016· ADVANTAGES: The first flotation machine in a copper-lead-zinc separation would produce a copper-lead concentrate. This copper-lead concentrate would go to a second machine wherein the copper w’ould be floated off, leaving a high-grade lead residue. Since the amount of copper-lead concentrate being treated would be small as compared to the original tonnage of the mill, excessive flotation capacity would not be required, as would be in the case of this 3 product flotation …

The effect of copper sulphate addition on the recovery of ...

copper sulphate prior to collector addition could cause the chromite to be hydrophobic and hence amenable to true flotation (Wesseldijk et al. 1999). The presence of chromite in the concentrate can result in inefficient smelter operations since it is a member of the spinel group that forms compounds that are stable to temperatures of up to 2000°C (McKenzie, 1996). As a result, …
