    01/01/2016· Cyanidation of gold ores with copper minerals is discussed in detail in Chapter 43 An interesting methodology, using thermodynamic constants and solution analysis, was proposed to explain the deportment of cyanide in gold plant liquors and solids (Adams, 2001) The speciation of cyanide with metals and the formation of thiocyanate are part of the approach The CyanoStat was the firstgold by sulphide minerals In practice, this means that below the critical concentration of cyanide, gold extraction decreases significantly The Musselwhite Mine plant, originally designed at 3,300tpd, processes a free milling gold ore containing pyrrhotite as the primary sulphide, at a present throughput of 3,650t/d The ore is crushed in twoCyanidation of a pyrrhotitebearing gold oreFor example, a gold cyanidation plant has a copper grade of 0548% in raw ore, and the mother liquor of the first leaching contains 1161mg/L copper, which consumes 376% of the annual cyanide consumption Due to the high copper content of the dissolving solution, in order to maintain the gold leaching activity of the solution, the sodium cyanide concentration in the slurry must be increasedHow to Reduce Sodium Cyanide Consumption of Gold

    20/10/2014· Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative A paper published by L Elsner in 1846 first correctly identified the chemical reaction that forms the basisIn short, the cyanidation process is to dissolve the gold in the ore through cyanide, then adsorb it through activated carbon, use electrowinning, become gold mud, and finally become a gold bar 2 Disadvantages of cyanide But one of the biggest problem of gold cyanidation process is it will cause strict environment pollution The state has a variety of environmental protection policies, andCNFREE Gold Leaching Reagent compared to Cyanide ingold plants to recover cyanide and to remove and rec over CNsoluble copper contained in the ore, thus reducing cyanide consumption Additi onally, operational evidence exists in gold cyanidatio n(PDF) Cyanide Leaching of CopperGoldSilver Ores

  • INFLUENCE OF LEAD NITRATE ON CYANIDE LEACHING OF GOLD

    Extraction of gold from its ores by cyanide leaching has been the preferred method for more than a century because of its simplicity, cost efficiency and the high stability of cyanide Dissolution of gold and silver in alkaline cyanide solutions can be represented by the halfcell oxidation reactions (Cerovic et al, 2005): –Au + 2CN –Au(CN) 2 + e– (1) –Ag + 2CN Ag(CN)– 2 –+ e (2Gold ore Prominer maintains a team of senior gold processing engineers with expertise and global experience These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc, to achieve the processing plant of optimal and costefficient process designsGold Processing,Extraction,Smelting Plant DesignA "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 pretreatment in order for cyanidation to be effective in recovery of the gold A refractory ore generally contains sulfide minerals, organicGold extraction Wikipedia

  • Cyanidation of reef and surface gold ores

    these free milling gold ores during cyanidation, is not influenced by mixing of reef and surface ore material No statistically significant relationship exists between the achievable recovery by direct cyanidation and the head grade of the material fed No ideal ratio of surface ore to reef ore could be established It is recommended that these materials should be processed simultaneously toCyanide easily combines with many metals – making it useful in separating metals like gold from their ore How is cyanide used in mining? A sodium cyanide solution is commonly used to leach gold from ore There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads The cyanide dissolves the goldCyanide Use in Gold Mining EarthworksGold flotation, in the treatment of simple metal sulfide ore with less cyanide harmful substances in the ore, generally control the flotation pH = 7~9 with lime 22 Inhibiting the flotation of iron sulfide minerals When flotation of various nonferrous metal sulfide minerals (such as copper, lead, zinc, etc) with xanthate collectors, the ore usually contains a certain amount of ironLime in Gold Ore Mining Process | Flotation, Cyanidation
