Gold Recovery by Batch Cyanide Leaching Plant
PROCESS FLOWSHEET DESCRIPTION: Batch Gold Cyanidation-Leaching Plant. ORE TREATED: Small tonnages of high-grade gold-silver ores and flotation or Jig concentrates amenable to cyanide treatment, used for treating as low as one ton of concentrates per day. ADVANTAGES: Where the tonnage of ore or concentrates is too low for standard continuous cyanidation plants (usually less than […]
CCD – Counter Current Decantation Flowsheet
PROCESS FLOWSHEET DESCRIPTION: Continuous counter-current decantation cyanidation flowsheet. ORE TREATED: Gold and silver ores amenable to the cyanidation process and where economics justify plant outlay. ADVANTAGES: By producing the precious metals in bullion form, the highest net return is realized on many gold and silver ores. Where the tonnage available for treatment justifies the capital […]
Jig Gold Gravity Circuit and Whole Ore Cyanide Leach
PROCESS FLOWSHEET DESCRIPTION: Jig gold concentrates reground and cyanide leached. Mineral Jig in ball mill-classifier circuit for removing sulphides for fine grinding and subsequent cyanidation leach. ORE TREATED: Sulphide gold or silver ores where fine grinding of the sulphides is necessary to expose the gold or silver to the cyanide solution and where it is […]
Gravity Gold with Amalgamation and Cyanidation
PROCESS FLOWSHEET DESCRIPTION: Gold Mineral Jig in cyanide circuit with amalgamation of the Jig concentrates. ORE TREATED: Practically all ores treated by cyanidation and especially all ores containing coarse gold. ADVANTAGES: The Mineral Jig and Amalgamation Unit have a definite place in cyanide plants, as it has been found that the gold recovered by the Jig […]
Recover Gold by Jigging in Grinding Circuit
PROCESS FLOWSHEET DESCRIPTION: Gold Mineral Jig in grinding circuit (ball mill discharge) at center of gravity concentration plant. ORE TREATED: Various oxide and nonmetallic minerals not now recoverable by flotation. ADVANTAGES: Where fine grinding is necessary before gravity concentration, high tailing losses are unavoidable as slimed mineral is not efficiently concentrated and recovered by gravity […]

Coarse Gold Jigging & Coarse Sulphides Float with Fine Gold Rich Base Metal Flotation – 911Metallurgist
CIRCUIT PROCESS FLOWSHEET DESCRIPTION: Gold Mineral Jig and Flash/Unit Float Cell in a flotation circuit. ORE TREATED: Partially oxidized or mixed oxide and sulphide ores. ADVANTAGES: In several cases this flowsheet has been used with outstanding success on dump ore and stope fills. Non-floating oxide minerals and tarnished gold are recovered in Mineral Jig ahead of […]
Gravity Gold Recovery from Flotation Concentrate
CIRCUIT PROCESS FLOWSHEET DESCRIPTION: A Mineral Jig of the flotation concentrate regrinding circuit followed by selective flotation with amalgamation of Jig concentrates. ORE TREATED: Sulphide gold ores, principally those containing some values in copper or lead in addition to precious metals. This flowsheet is applied to ores containing large amounts of pyrite which contains intimately […]
Gold Mineral Jigging followed by a Flotation Circuit
CIRCUIT PROCESS FLOWSHEET DESCRIPTION: A Gold Jig ahead of the flotation circuit with or without amalgamation of the Jig concentrates. ORE TREATED: Most gold ores where flotation is used for final recovery. Lead or lead-silver ores containing coarse lead sulphides or lead oxide minerals, also pyritic ores containing gold and silver. ADVANTAGES: Although most gold ores […]
Gold Recovery Jig, Shaking Table and Amalgamation Process
CIRCUIT PROCESS FLOWSHEET DESCRIPTION: Modern, inexpensive amalgamation circuit with the Mineral Jig as the major recovery unit. ORE TREATED: Practically any gold ore containing native or free gold. ADVANTAGES From sixty to ninety-five percent recovery can be made with this simple flowsheet on many ores, and the gold produced in bullion form. The Mineral Jig […]
