The reaction sequence with xanthate is Chalcocite copper blue speckle copper pyrite 2 Secondary copper ore and oxidation influence 3 Influence of ded particles the fine of the particles the much difficult to make the flotation 4.
(d) Weight Recovery is essentially the inverse of the ratio of concentration and equals 100 C F = 100 (f – t) (c – t) (e) Enrichment Ratio is calculated directly from assays as c f weights are not involved in the calculation Example Calculations Problem A copper ore initially contains 2 09 Cu After carrying out a froth flotation.
Apr 13 2016 Copper minerals usually occur in low grade deposits and require concentration prior to smelting The method and degree of concentration depends on smelter location and schedules together with the nature of the ore deposit Sulphide copper ores generally occur with pyrite pyrrhotite arsenopyrite and molybdenite and with gold and silver A.
We have a range of spirals from 3 to 12 turns with high medium and low gradient profiles Our high capacity spirals (the HX series) provide a per start tonnage rating of 4 to 7 5 tons per hour depending on the mineral type and is especially suited for the treatment of low grade ore.
Copper (Cu) is an essential heavy metal for plants but high Cu concentration in the soil causes phytotoxicity Some plants however possess a system that can overcome Cu toxicity such as Cu localization and an active antioxidant defence system to reduce oxidative damage induced by high Cu concentration.
Which will help you to decide where to drill Copper grade is the concentration of copper in the ore rock To calculate the grade of copper for the sample geologists use the equation (amount of copper metal amount of copper ore rock) 100 2 If a deposit area has 200lbs of copper in 10 000lbs of ore rock what is the grade 200 10000 100=2 3.
