    2 17. Flotation of Gold Ores. also for beneficiation and separation of difficult-to-treat (refractory) gold ores. Flotation is also the best method for recovery of gold from base metal ores and gold-containing PGM ores. Excluding gravity preconcentration, flotation remains the

  • Flotation of Gold and Gold-Bearing Ores ScienceDirect

    01/01/2016· Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold recoveries. When pyrite is present in the

  • Gold Flotation Mineral Processing & Metallurgy

    13/07/2016· GOLD FLOTATION FLOWSHEET. It is obvious that the most suitable treatment for ores carrying gold and silver associated with pyrite and other iron sulphides, arsenopyrite or stibnite, will depend on the type of association. Cyanidation is usually the most suitable process, but it often necessitates grinding ore to a fine size to release the gold and silver. Where it is possible to obtain a

  • Carbonaceous Gold Ores Treatment Process

    Application of IX resin can be beneficial in this case for two reasons, at least. IXR is resistant to organic fouling, including kerosene. Having high affinity for aurocyanide the resin removes gold from the solution and so shifts leach equilibrium to favourable side. Thus, gold recovery from ore becomes few % higher. The resin of choice may be Purolite A194 either Dowex XZ91419. Both are commercially used

  • Refractory Gold Ore Treatment Methods

    14/07/2016· The later development of flotation for gold ores, has, in most cases, provided a satisfactory pretreatment and has been applied in several ways. Flotation removes most of the freed carbon with the concentrate, which is then roasted prior to cyanidation or shipped to a smelter. McIntyre, using flotation with cyanidation of concentrate, refloated their cyanidation tailing and returned this

  • Optimisation of gold recovery by selective gold flotation

    Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides. This may be an alternative treatment route for gold room applications where fine gold

  • Silver Gold Recovery Flotation Process

    17/10/2016· The two installations just described are typical of the way in which flotation is being applied in the metallurgy of gold ores. Although it is scarcely possible at present to point to a standard mode of procedure in their treatment, the fact has been established that flotation is of definite value as a means of reducing costs by concentrating into a small bulk gold-bearing minerals which require fine grinding

  • Establishing thE ProcEss MinEralogy of gold orEs

    gold ores can be classified into 11 types (Table 1). Some metallurgical implications to these gold ore types are summarised below: Placers, quartz vein gold ores and oxidized ores: Generally, placers, quartz vein gold ores and oxidized ores are free-milling and gold can be recovered by gravity and/or direct cyanide leaching. Some epithermal deposits may be free-milling (such as the

  • Flotation kinetics of a pyritic gold ore ScienceDirect

    17/01/2011· Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant is more sensitive

  • Enhanced flotation of refractory gold ore by using sulfur

    01/07/2016· Then the gold ores contain enough gold particles to form agglomerates. As a result, the fine gold particles in the beginning are converted to the masses in the form of sulfur-gold-oil which are bonded together by liquid bridges. Meanwhile, the sulfur could strengthen the adsorption of collectors on gold surface, as well as the floating size range of gold is widen, and the recovery of gold is significantly

  • Flotation kinetics of a pyritic gold ore ResearchGate

    The practice of the flotation of pure gold and gold-bearing ores such as tellurides, aurostibite, kerogen, pyrite, pyrrhotite, copper-gold ores and mixed sulphides is reviewed. The factors which

  • Refractory Gold SGS

    The other parameter that SGS experts consider when designing refractory gold treatments is whether or not to preconcentrate the gold-bearing ore. This is usually done by flotation of arsenopyrite, pyrite, or other gold-bearing sulfides. To be economically justifiable, preconcentration should meet two objectives. First, the gold recovery to the concentrate should be sufficiently high that the tailings can be

  • Gold extraction Wikipedia

    A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold. A refractory ore generally contains sulfide minerals, organic carbon, or both. Sulfide minerals are impermeable minerals that occlude gold
