  • Enhanced methods for nickel recovery from low

    Smelting is the next stage, designed to recover as much metal as possible Flash smelting is a common method: dry concentrates are fed into a furnace and heated to a liquid matte and slag From this step, sulfide matte can be recovered, which contains cobalt, and nickel (about 70%) Iron is recoveredRecovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine In openstope mines the greatest loss of ore is that tied up in pillars left for support of the back orOre Dilution & Recovery in Mining

  • Gold Extraction & Recovery Processes

    There are some considerations related to the concentration process Recovery is the percentage of gold in the raw ore collected in the concentrate For example a recovery of 85% means that 85% of the gold is reported in the concentrateSome 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 freemilling and gold can be recovered by gravity and/or direct cyanide leaching Some epithermal deposits may be freemilling (such as theEstablishing thE ProcEss MinEralogy of gold orEs

  • Upgrading of Iron Concentrate by FluidizedBed

    Efficient use of abundant lowgrade siderite ores can potentially mitigate the shortage of iron ore in the iron and steel industry in China In this work, the beneficiation of siderite fines containing high levels of carbonates was studied using a combined fluidizedbed magnetizing roasting process The siderite was almost completely converted into magnetite under the optimum conditions ofImportant advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function The paper demonstrates the application of this methodology to optimize solids concentration in ball milling of an iron oreOptimization of Solids Concentration in Iron Ore Ball
