  • Flotation And Sintering Of Synthetic Manganese Carbonate

    A process in which manganese is recovered from manganese nodules after the nodules have been treated to recover base metals such as copper, nickel, cobalt, and molybdenum. The process includes the steps of reacting the manganese in the nodules to yield a carbonate and subjecting the manganese carbonate to flotation. The manganese carbonate froth is collected from the top of a flotation cell.

  • New Flotation Technology Research On Carbonate

    A new flotation technology of carbonate-containing hematite was introduced in this paper, The results show that iron minerals are mainly composed of hematite, siderite, magnetite, limonite, ankerite, quartz, hornblende, and a small amount of chlorite, etc. The increase of iron carbonate can deteriorate the normal flotation of hematite, but now a new flotation technology can weaken the negative.

  • Flotation Depressants Arrmaz

    ArrMaz’s flotation depressants have been custom developed for a variety of applications. They help depress gangue minerals while increasing recovery and selectivity without sacrificing grade. Our depressants have been especially effective in phosphate, silica glass sand and iron beneficiation.

  • A Review Of Flotation Separation Of Mg Carbonates

    These depressants partially affect Mg carbonate flotation by changing pH value. pH, collector, and depressant concentrations are the main parameters for a selective Mg carbonate separation. For instance, it has been reported that thioglycollic acid and citric acid selectively depressed pyrite between pH 9.0 and 10, but could not depress.

  • Selective Flotation Of Phosphate Carbonate Ores

    The observed optimum flotation of calcite and dolomite by carboxylic acids as a function of the starch consumption, and the subsequent depression of flotation, may be chiefly due to the adsorbed conformation structures of the starch molecules to the strength of the hydrogen bonds with the surfaces of hydrated minerals.

  • Method Of Floating Calcium Carbonate Ore And Flotation

    We claim 1. A method of cleaning calcium carbonate ore containing silicate impurities which comprises subjecting said ore to a froth-flotation process in the presence of a cationic collector, wherein the collector is a combination of a quaternary ammonium compound having the formula STR3 wherein one or two of the group R 1, R 2, R 3 and R 4 are selected from a hydrocarbon group having 8.

  • Flotation Of A Carbonate Rich Sedimentary Phosphate Rock

    These are the most difficult type of deposits to beneficiate. The depletion of other reserves easier to beneficiate, necessitates research to find methods of mineral processing for carbonate rich sedimentary phosphate deposits. In this study, a new flotation method is described which was applied successfully in a laboratory scale flotation cell.

  • Sequential Separation Of Carbonate And Siliceous Gangue

    The process involves a first stage of selective carbonate phosphate separation followed by phosphate silica separation during the second stage. In the first stage, a carbonate rich froth is removed without specific depression of the phosphate minerals and without conditioning of the pulp with the fatty acid collector prior to flotation.

As a result, when chromate salts are added to a galena system, the formation of lead chromate on the galena surface will occur. Depression is ascribed to the strong hydration of chromate adsorbed on the surface. 4.
