flotation process selective in indonesia

Abstract This invention provides a process for improved separation of monomultimetallic sulphide minerals from significant amounts of iron sulphidess mainly pyrrhotite andor their finely divided process middlings The process comprises subjecting such material to a conditioning stage with at least one watersoluble sulphurcontaining inorganic compound as a prerequisite step for further

Therefore flotation and leaching both of which are the first stage of each scenario of finelyground ores are of crucial importance to assure the continued supply of metals This Special Issue will be devoted to collecting papers on recent advances in selective flotation and leaching processes for

The invention relates to a process for the selective flotation of phosphorus minerals in which process the flotation collectors used are one or more compounds of the formula 1a andor 1b STR1 wherein R 1 is a branched or straightchain C 8 C 24 in particular C 8 C 18 alkenyl R 2 is a branched straightchain or cyclic alkyl having 5 andor 6 carbon atoms and M is hydrogen an

Salah satu perusahaan tambang terkemuka di dunia PT Freeport Indonesia melakukan eksplorasi menambang dan memproses bijih yang mengandung tembaga emas dan perak di daerah dataran tinggi di Kabupaten Mimika Provinsi Papua Indonesia Kami memasarkan konsentrat yang mengandung tembaga emas dan perak ke seluruh penjuru dunia

Jun 10 2016 · Selective flocculation process has been commercialised for iron ore to process finely disseminated large deposits of oxidised taconites containing predominantly hematite and goethite Colombo 1986 The process involves dispersion of mineral particles with sodium hydroxide and sodium silicate–lignosulfonates–hexametaphosphate or tripolyphosphates followed by selective

The use of flotation is showing a great potential due to the high throughput of modern equipment low sludge generation and the high efficiency of the separation schemes already available It is concluded that this process will be soon incorporated as a technology in the minerals industry to treat these wastewaters and when possible to

As an effective and economic pH modifier lime is widely used in the process of selective flotation of the major sulphide minerals This paper reviews lime preparation factors that influence the

flotation rate particle size recovery air flow pulp density etc As a result it is difficult to study the effects of any single factor in isolation and compensation effects within the system can keep process changes from producing the expected effects Klimpel 1995 This makes it

A range of surfactants have been compared for use as foaming agents in froth flotation for removal of wood extractives from thermo mechanical pulp TMP process water The surfactants studied were dodecyltrimethylammonium bromide DoTAB

Fluorite is an important strategic mineral In general fluorite ores will contain a certain amount of calcite gangue mineral Thus they need to be separated from each other For an economic separation a reverse flotation process is used to float calcite gangue from fluorite However little information on the separation is available In this study a novel reagent schedule using citric acid
