Onsite ore samples used for flotation and magnetic separation were collected from the Sijiaying Iron Ore Mine dressing plant and were transported to the laboratory after filtration and drying The iron grades of the ore samples prepared for flotation and magnetic separation tests were % and % respectively
Intimate knowledge of the mineralogical assembly of the Yushui complex ore rich in Cu Pb and Ag is essential if efficient separation processing is to be conducted With the aid of testing instruments such as scanning electron microscope SEM X ray diffractometer XRD and mineral liberation analyzer MLA combined with energy dispersive X ray analysis
The possibility of using a thermomorphic polymer with a phosphine group as a collecting reagent for the selective concentration of tin during flotation enrichment of sulfide tin tails was first investigated in the work A detailed description of the experimental scheme of flotation concentration of sulfide tin ore tailings and the reagent mode are given
Manganese ore dressing fire enrichment Why Producers Like It ① It can effectively separate iron and phosphorus from ore and obtain the manganese rich slag with low iron and low phosphorus ② The process is simple and stable The ore through the flotation process can be sintered which greatly improves the grade of manganese ore 7

The mixed concentrate containing Cu % and Pb % was preoxidized under the above conditions and the flotation separation verification results showed that Cu concentrate with Cu grade of
Problem A copper ore initially contains % Cu After carrying out a froth flot ation Starch adsorption in iron ore flotation is key for the effective depression of hematite It has been
The study covers 16 samples from Cu flotation feed Cu rougher concentrate Cu final concentrate and Cu rougher tail sieved in 4 classes each > 36 µm 36 20 µm 20 9 µm and 36 of Cu final concentrate where the total amount of Fe Cu is wt % compared to wt % for the whole Cu final concentrate and wt % compared to
the flotation recovery of Ni Cu and Co from a nickel copper sulphide ore The effect on flotation performance of various parameters such as pH collector dosage % solids and depressant dosage at different levels was investigated Therefore the main objective of the study was to optimize the process parameters for the flotation of base metals
Abstract The authors discuss application of nitrogen oxygen sulfur heterocyclic agents as collectors and frothers in flotation of sulfide minerals Efficient collectors are the compounds which contain nitrogen heteroatom and sulfur atom in pendent group they can generate complex compounds including chelate with copper antimony and other metals

A case study of flotation of a complex Cu Zn sulphide ore is outlined Download to read the full chapter text Chapter PDF Petruk W 1987 Applied mineralogy in ore dressing in B Yarar and Dogan eds Mineral Processing Design
For the complex and refractory low grade Cu Mo Bi W Au and Ag ore a process flow sheet applied is bulk flotation of sulfide minerals Cu Mo and Bi S separation of rough
Pulp Densities Pulp densities indicate by means of a tabulation the percentages of solids or liquid to solid ratio in a sample of pulp This figure is valuable in two ways—directly because for each unit process and operation in milling the optimum pulp density must be established and maintained and indirectly because certain important tonnage calculations are
Froth flotation process and its application Sangita Mondal1 Animesh Acharjee1 2 Ujjwal Mandal1 Bidyut Saha1 Cu etc Often before roasting the ore generally sulfide ores is partially purified using another important technique which is called froth flotation and it is the topic of our discussion as well Froth flotation is such
Iron tailings are a common industrial solid waste and with the development of society and continuous progress in ore dressing technology the stockpile of iron tailings is increasing copper zinc separation zinc flotation iron magnetic separation reverse flotation of iron concentrate" to recover Cu Zn Fe and associated precious
Ores amenable to concentration by flotation Almost any ore consisting of a mineral of metallic resinous or adamantine luster associated with the usual rock forming minerals can be concentrated by flotation The volume of gas effectively utilized in floating the mineral is of the order of 20 to 50 cu ft per cu ft of solid floated 1
Simultaneously the iron grade and level of SiO2 Al2O3 impurity in the iron ore product from reverse flotation of the low grade iron ore with DTAB collector reached mass% and mass% which
This chapter describes production of Cu rich sulfide concentrate ∼30% Cu from finely ground ore Copper sulfide ores must be concentrated before they can be economically transported and smelted
