  • Pyrite Flotation Froth Flotation (Sulphide & Oxide

    Can you list the factors affects the floatability of pyrite from refractory low grade ore. I used a Wemco lab flotation cell and aimed on analysing factors like collector dosages (PAX), Activator (Copper sulphate),MIBC,pH and others like pulp density and particle size (70 and 150 microns) .However how these factors affect the floatability of the pyrites from low grade refractory ore.

  • Flotation of Pyrite Metallurgist & Mineral Processing

    In order to determine the effect of size of mineral grains on the flotation of pyrite, sample mixture No. 4 was thoroughly mixed and a number of 500-gm. portions weighed out. Tests were then made using the four oils or mixtures that gave the best results on the more finely ground sample. Sizing tests showing the distribution of the pyrite both before and after flotation are given in Tables 7

  • Pyrite Tailings Recovery by Flotation

    Pyrite has long been used as a source of sulphur, and its recovery as a by-product from the flotation of certain base metal ores is a well established practice. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings can be treated to yield pyrite concentrates that are a

  • Pyrite Depression in Copper Flotation

    The Pyrite Depression in a Copper Only Flotation circuit is simple enough. If your froth flotation system only tries to recover chalcopyrite-copper, you need to bring the plant’s pH up to the other side (right side) of the PYRITE curve. The more flotation collector you have on, the higher you will need to increase that pH for effective pyrite depression. You also need to insure your pyrite

  • Gold Pyrite, Pyrrhotite and Arsenopyrite Recovery

    In this author’s experience, arsenopyrite/pyrite systems have a tendency to be unique to a given ore body so that what works with one ore does not always work well with other ores. Copper sulfate is often used as an activator in the flotation of gold associated with iron sulfides. Experimentally, when copper sulfate is used in the flotation

  • New collectors for sphalerite flotation Request PDF

    Bench-scale flotation tests were done with a chalcopyrite, sphalerite and pyrite-containing ore from Timmins, Canada using p-nonylcupferron as collector. Effects of pH and the need for adding

  • Copper and Pyrite Separation by Selective and Sequential

    The ore from the fine ore bin, delivered at a uniform rate by a Adjustable Stroke Belt Ore Feeder, is ground to minus 65-mesh in a Ball Mill operating in closed circuit with a Spiral Classifier. Reagents are added to the ball mill-classifier circuit for proper depression of the pyrite during the flotation

  • Pyrite an overview ScienceDirect Topics

    Pyrite (FeS 2) is commonly associated with other valuable metal sulfides, and with precious metals. In particular, some gold ore deposits contain the gold as particles embedded in grains of pyrite. In order to leach the gold, the pyrite must be roasted under controlled temperature and pO 2, such that only hematite (Fe 2 O 3) is present in the

  • Processing of Konkola copper concen- trates and Chingola

Bowes‡ Synopsis The Konkola Deep Mining Project (KDMP) seeks to exploit the deep level potential of the Konkola Deeps orebody, producing high grade

  • What Is Direct Flotation In Mineral Processing- LEMINE

    Introduction To Mineral Processing. Introduction to mineral processing the process of froth flotation entails crushing and grinding the ore to a fine size this fine grinding separates the individual mineral particles from the waste rock and other mineral particles the grinding is normally done in water with the resultant slurry called the pulp

  • Gangue Mineral an overview ScienceDirect Topics

    If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.

  • The role of sodium metabisulphite in depressing pyrite

    The single minerals, chalcopyrite and pyrite, were obtained from GEOdiscoveries, Australia. Their elemental compositions were analysed by ICP-MS and shown elsewhere (Mu and Peng, 2019).The XRD patterns of chalcopyrite and pyrite samples are shown in Fig. 1(a) and (b), respectively. The impurities in chalcopyrite are mainly quartz and a small amount of sphalerite and the impurity in pyrite is

  • A technique to determine ore variability in a sulphide ore

    Therefore, ore variability across the entire ore deposit was evaluated using the relationship between Oxidation Index and flotation performance. The results showed that this methodology can potentially be used as a practical and cost effective method for mapping an ore body regarding variations in surface chemistry of sulphide minerals, prediction of flotation recoveries and selectivity.


    Flotation pyrites are, however, obtained in marketable quantities as a byproduct of nonferrous metal sulfide beneficiation plants. Figure 1: Source and Demand for sulphuric acid plants The roasting processes as shown in Figure 1 are related to the fluid bed reactor. The largest single line stationary fluid bed roasting plant in operation today has a capacity of 1,130 t/d of pyrite/pyrrhotite
