  • Copper Nickel Flotation

    The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct Cu and 0.11 pct Ni and the shaft sample analyzed 0.69

    Jun 01, 2018· The best flotation result was for the S ore sample where nickel upgraded from 3.0% up to 4.2% (i.e. by 40%) at around 70% when HDMA was used. This is considerably better than nickel flotation grade and recovery data reported in the literature for this type of ores (i.e. saprolite) . Based on these data, the best condition to upgrade nickel in

  • role of sodium hexametaphosphate in flotation of a nickel ore

    The nickel grade of the ore sample used in this study was 1.35%. Approximately 96% of the nickel in the ore was in the form of pentlandite, and could be recovered by true flotation. The remaining 4% of nickel distributed in non-sulfide minerals, which could only be recovered by the entrainment mechanism or as composites with pentlandite.

  • The beneficiation process of nickel ore,copper-nickel

    The flotation of copper-nickel ore has the following four basic processes. Directly use priority flotation or partial priority flotation process: When the copper content in the ore is much higher than the nickel content, this process can be used to select copper into a separate concentrate. The advantage of this process is that copper

The effect of sodium carbonate on the flotation performance of a nickel ore was studied and the mechanism investigated. The flotation results show that lizardite minerals in the ore interfere with the flotation of pentlandite,

  • Froth flotation Wikipedia

    Froth flotation is a process for selectively separating 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.

  • Enhanced methods for nickel recovery from low-grade ores

    All nickel ores have relatively low nickel content, the classification is as follows: high-grade nickel ore has Ni content greater than 1.8%, middle-grade nickel ore has Ni content between 1.3-1.7%, low-grade nickel ore has Ni content between 0.6-1.2%. Nickel is continuously mined, even at these low percentages of ores, because it is in high
