    EFFECTS OF FLOTATION VARIABLES ON FELDSPATHIC SAND ,, Therefore, the flotation resulted in hardly any quartz, but there was also less feldspar and recovery became increasingly lower A range of 750-850g/t would seem to be the optimum HF concentration, since both grade and recovery would be close to a maximum 33 Effects of pre-flotation pulp conditioning ,Some aspects of coal flotation at washeries of Tata Steel, of pulp density control of flotation feed During trial operations, many a times, it was not possible to achieve the optimum pulp density Two stage pumping of flotation feed became necessary to suit topographical situations of flotation feed sump and the entry point of pulp to the conditioner Tell-tale sieve bends to indicate possible migrationDecoupling the Effects of Pulp Potential and pH on the ,, on Flotation To determine the effects of pulp pH on the flotation recovery of the pyrite mineral, representative subsamples were conditioned and floated at pH 4, 64, 8, 92 and 11 Conditioning of the pulp was carried out at the set pH and allowed 5 mins to ,The Role of Coarse Conditioning Drums in Potash Flotation, Aug 05, 2020· Also called reagentizing, conditioning is a critical step in potash froth flotation (and also in many other industries that use froth flotation, such as when liberating phosphates) Conditioning combines various reagents with the pulp in order to enhance the hydrophobic or hydrophilic nature of the materials, ultimately improving separation ,Flotation pulp conditioning intensity determination and ,, The importance of pulp conditioning prior to flotation, and the methods for obtaining "best conditions" for selective hydrophobicity is presented Traditionally, only the amount of reagents and ,.

    Method of flotation of sulfide copper, (57) Abstract: Usage: mineral processing, in particular flotation of copper-zinc sulphide ores and products Method of flotation of sulfide copper-zinc ores includes the conditioning of the pulp in a calcareous environment with reagents-regulators sulfur, sodium, and zinc sulfate, the introduction of collector and Frother and subsequent separation with separation of copper minerals in the ,INTERPRETATION OF FLOTATION DATA FOR THE DESIGN ,, Variables that are subject to control include grinding factors such as fineness of grind, pulp density, type of grinding medium, and chemical additives; conditioning factors such as collectors, depressants, pH, time, intensity, and temperature; and flotation factors such asTECHNICAL NOTES 9 FLOTATION, The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase The water in the flotation cell is conditioned to promote the formation of a more or less stable froth The bubbles do not burst when they cross the interface and each one carries a skin of water into the froth phaseThe effect of conditioning on Froth Flotation, conditioning effects were to be isolated from the complicating factors of the flotation pulp and froth phas Hence the measurement of conditioning was divided into two aspects: 1) The measurement of collector adsorption 2) The measurement of flotation response of given levels of adsorption(PDF) Flotation and depression control of arsenopyrite ,, As seen in Fig 3, the EH values at the arsenopyritic ore as a function of pH using 30 and the end of the flotation tests are higher than those in the conditioning step, which is due to oxidation of the pulp by the oxygen in the air used for flotation.
