Establishing the elemental composition and grade of base metal ores is carried out at different stages of mining and processing. It is used in advanced exploration to confi rm the feasibility of mining the ore, and in the assay of the ore concentrate. The determination of the concentration of base metals requires a technique with good accuracy and precision that is capable of generating and man...

The effectiveness of jigging operation for the beneficiation of low-grade iron ore deposits of Orissa, India has been investigated. Iron ore sample obtained from Barbil region of Orissa containing very high amount of silica and alumina was crushed using the laboratory jaw crusher and roll crusher to prepare different particle sizes. The sink and float tests were carried out to evaluate the poss...

The research is aimed at study of the probable recovery iron from tailings Olcon mining company located in north-western Arctic zone Russia. Material composition a sample dump was analysed. authors have developed separation production technology to recover magnetite-hematite concentrate tailings. A processing flowsheet includes magnetic separation, milling and gravity concentration methods. pro...

This paper studies the properties of metallurgical briquettes iron ore concentrate with coke screenings and liquid glass as a binder. The are produced by one-sided pressing in closed die mounted on plates vertical press force 100 kN. were carried out laboratory Spidermash LLC. following determined: density, impact strength compressive (for green dry briquettes). functional dependences mechanica...

This article investigates the effect of material size on efficiency flotation concentration gold-copperarsenic ores Taror deposit (Republic Tajikistan) and studies dependence gold recovery duration process with purpose developing an alternative technological scheme for processing this ore type. According to X-ray phase analysis, samples consist rock-forming minerals by 92%. Ore mineralization i...

May Concentrate Iron ore, as a refractory iron concentrate, deteriorates the permeability of sintered layer during sintering process due to its fine particle size and poor granulating performance. Therefore, it cannot be widely used in ore sintering. In this study, strengthening granulation using pre-pelletizing expand utilization ratio was proposed. The experiments conventional granulation, si...

Bama is one of the major concentrating plant in Iran which treats nearly 1500 tons per day sulphidic lead and zinc ore. Large amount of oxidized ore exist in Bama which has been extracted along with sulphidic ore. The main objective of the present investigation was the up-grading of the ore from Goshfil which is the major deposit in Bama. The ore contained about 16% zinc as smithsonite, about 1...

In this study, enrichment possibility of apatite-bearing iron ore sample was investigated to obtain and phosphate concentrates, separately. It determined that the raw contains 35.75% Fe 5.36 P2O5. Magnetite from can be enriched with low field strength wet magnetic separators, apatite magnetite residues by flotation. For purpose, ground minus 106 m size then subjected separation following Accor...

This study investigates an unusual source of environmental lead contamination - the emission and deposition of lead and zinc concentrates along train lines into and out of Australia's oldest silver-lead-zinc mine at Broken Hill, Australia. Transport of lead and zinc ore concentrates from the Broken Hill mines has occurred for more than 125 years, during which time the majority was moved in unco...
