Particularly grinding to achieve liberation since this is the most energy intensive operation in beneficiation and the overall recovery since losses along the valueadding chain require more ore to be mined per unit of metal produced. Figure 1 The embodied energy of
The inhibitors used in the investigation were sodium sulphite sodium nitrite sodium chromate and sodium silicate. The results indicate that a specific corrosion inhibitor for example sodium sulphite may give better recoveries and grades in flotation but is not as efficient as sodium chromate in inhibiting the wear of the grinding media
inc sulphide ores from various sites. Pyrite is the main sulphide gangue mineral in the Rosh Pin composite sample. Traces of chalcopyrite gold and silver are found in the ore sample Figure 1. At the Rosh Pin plant the composite feed is processed by selective flotation in which galena is floated first with sodium
Practice and discussion on grinding technology for treating refractory oxidied lead inc ore in lanping The authors analye the ore potentiality which may provide a good base both on theory and practice for further
Role of Sodium Sulfide Copper Lead Zinc Ore Flotation. Role of Sodium Sulfide Copper Lead Zinc Ore FlotationSodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper lead and inc minerals in their oxidied form The sulfidiation process developed in the USA in 191520 for oxide copper minerals flotation is especially suitable for oxidied lead ores in
The results indicate that the recovery rates of lead and inc in mixed concentrate were and respectively the recovery of inc in coarse concentrate was in the open circuit experiment Under the conditions that the grinding fineness of 0
Studies on grinding media wear and its effect on flotation of ferrugenous phosphate ore Studies on grinding media wear and its effect on flotation of ferrugenous phosphate ore Deshpande Natarajan 000000 Marked ball grinding tests were carried out in the laboratory with a low grade phosphate ore under different experimental conditions
Grinding the ore too fine will produce slimes or very fine particles which are difficult to recover in the separation process and are usually lost to tailing. Lead and Zinc Ore Concentration If the mineral veins separate from the rock cleanly then processing workers can concentrate the
Under the control of grinding fineness with 74 m in 80 the flotation flowsheet is determined consisting of oneroughing threeconcentrating and onecleaning floating copper from raw ore and oneroughing threeconcentrating and twocleaning floating inc
Under the same grinding conditiongrinding aids such as sodium carbonatecalgonRChydraine hydrate and triethanolamine were introduced for bauxite grindingand their effect on the grinding efficiencynamelythe yield of16 m sie fraction in the grinding product
Electrochemical Aspects of Grinding MediaMineral Interaction in Sulfide Ore Grinding sodium carbonate solution for 2 min to remove mineral par and conditions has been used to examine the
ore contains less than per cent total sulphide. The results show that the change to an inert media type produced a substantial improvement in the flotation rate of all sulphide minerals as well as the PGMs. Figure 1.

Potential during Leadinciron Sulfides Grinding availability is high. of reducing slime of oxidied inc ore by using stirring mill has been carried out.
Of sodium sulphide 1000 2000 3000 gt were used in the flotation experiments. The concentrate grade and recovery of inc ore flotation for various amounts of DDA with sodium sulphide 2000 gt as sulphidiing agent are shown in Figure 2. The recoveries of all inc ore flotation products during the different times were calculated

History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper Lead Zinc Nickel Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique. This technology has acclaimed importance as a versatile process for

For example sodium cyanide can be used as a depressant in the separation of inc sulphide ore ZnS and lead sulphide ore PbS. Sodium cyanide forms a layer of inc complex Na 2 ZnCN 4 on the surface of ZnS and therefore prevents it from forming the froth. Therefore it acts as a depressant. 4 NaCN ZnS Na 2 ZnCn 4 Na 2 S
