What Is Differential Flotation Process For Nickel And Sulfur

Similarly, the use of other depressants such as cyanide has proven to be unreliable for separating the two minerals. There is presently no known successful commercial application of a pyrite arsenopyrite differential flotation process. The use of sulfur dioxide for depressing sphalerite (ZnS) during the flotation of pyrite is well established.

    Froth Flotation Process Mineral Processing & Metallurgy

    A sequential flotation process for the recovery of high grade concentrates of copper, lead and cobalt nickel from sulfide ores is provided. A primary grind ore pulp is conditioned with SO 2 as H 2 SO 3 under intense aeration, and the conditioned pulp subjected to sequential flotation, with regrinding and conditioning of a copper rougher concentrate obtained in the first flotation step for copper.The process involves a series of flotation known as the differential flotation. In the flotation of copper zinc massive sulfide ores, flotation properties of copper and zinc are determined by the nature and composition of the ore. Copper zinc massive sulfide is even regarded as the most complex ore and consequently the most difficult to treat.

    Production Of Nickel Concentrate From Ground Sulfide Ore

    Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics. Because an ore typically has than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance.However, the poor nickel floatability into the bulk concentrate indicated that TBP can be an effective flotation reagent for differential flotation of Cu Ni bearing concentrates to preferentially depress pentlandite. TBP is likely to play duel role in augmenting the copper recovery while depressing the nickel sulphide minerals.

    1 Froth Flotation – Fundamental Principles

    When floatability difference happens to the various nickel elements in the raw ore, the nickel ore can be recycled from tailings after the copper and nickel did the mixing flotation. Copper Nickel Ore Flotation Process A basic principle of copper sulfide nickel ore process is that it is better to let the coppers assimilate into the nickel ore.Flotation rate, particle size recovery, air flow, pulp density, etc.) As a result, it is difficult to study the effects of any single factor in isolation, and compensation effects within the system can keep process changes from producing the expected effects (Klimpel, 1995). This makes it.

    Aug 21, 2020 Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas. This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is \[2CuFeS_2 + 2SiO_2 +4O_2 \rightarrow Cu_2S + 2FeSiO_3 + 3SO_2 \label{1}\] The copper(I) sulfide produced is converted to copper with a final blast of air.The froth flotation process can not only enrich maximum gold into the sulphide mineral concentrate, but also discard the tailings, so the processing cost is low. Besides,froth flotation method can also be used to polymetallic gold mining, such as gold copper, gold lead, gold antimony, gold copper lead zinc sulfur.

    Eight Factors Affecting The Flotation Process Xinhai

    Jul 28, 2019 The Mond (or Carbonyl) Process is the most common and efficient method to treat nickel sulfide. In this process, the sulfide is treated with hydrogen and fed into a volatilization kiln. Here it meets carbon monoxide at about 140F (60C ) to form nickel carbonyl gas. The nickel carbonyl gas decomposes on the surface of pre heated nickel.The addition of lime in the flotation operation is usually carried out by adding the lime powder to the ore belt of the ball mill or adding lime milk or lime powder to the stirring tank before the flotation. The role of lime in the flotation process is most apparently the effect on the properties of the flotation foam.
