Extraction of Metals from Ore. A method for upgrading ferrometallic ores via selective carbothermic reduction and smelting (SCRS) process is useful for concentrating and extracting metals from ore containing iron and other metals.
The method includes dry crushing, crumbling of ore to the size of 6095% class 0.074 mm, floatation concentration of crushed ore with extraction of the copper sulphide minerals concentrate at the first stage, while at the second stage copper oxidised minerals concentrate is extracted from the rest ore.
Under these conditions, recovery of Mn was 98%, and the leached residues were analyzed. The present process may find appliion of separation of manganese from iron and aluminium at high temperature during various hydrometallurgical treatment of manganese based ores.

the pH 10.5 is necessary for complete removal of manganese (Sheremata and Kuyucak, 1996). The literature review showed that to the issue of selective extraction of metals from acid mine water is given considerable attention. Jenke and Diebold (1983) reacquire the metals from AMD by adding sulfide and subsequent oxidation and selective titration.
Pump leaching is a process that grind gold mine with low grade to a certain particles, heap up on the leakageproof bottom mat that concreted by pitch, concrete or plastic cloth, spray the low concentration cyanide solution, alkaline solution, nontoxic solvent, dilute sulphuric acid on the stock heap, make the gold dissolve, the solution with gold heap up, then use active carbon
 Further, step (I), the manganese oxide may be a mixture of one or more of manganese oxide ore soft, hard manganese ore, manganese and other black or brown manganese in the manganese manganese oxide may be via after crushing and screening ore, after high grade ore dressing, lowgrade or tailings in one or more of a mixture.
Lowgrade manganese ore from Sandur, India containing 28.2 per cent manganese and 20.9 per cent iron was roasted with sulphating agents, viz ammonium sulphate and sulphuric acid. The effects of temperature of roasting (300 – 800°C), time (15 – 120 minutes) and amount of sulphating agent (0.5 to 2.5 times stoichiometric amount) were studied.
A process for recovering manganese from lowgrade manganese oxide ore through a reduction acidolysisselective leaching method is investigated. Two

excellent cobaltnickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative if the ore can be concentrated by flotation, matte smelting is used instead of leaching.
Manganese Ore Concentration by Flotation. The slime fraction of the ore overflowed by the hydraulic classifier and by the rodmill spiral classifier is thickened in a Spiral Rake Tray Thickener for treatment by flotation. The flotation circuit is designed to treat three classes of manganese ores. Those ores with a high calcite gangue.

Geological section . both mastering the technology for processing the lower grade carbonate ore and on in troducing are developed by the Government to guide the course of the manganese . ly considering the South African situation.
For example, almost half of the manganese ore resources in India are ferruginous and more than 73% of the manganese ores in China belong to FeMn ores with a low Mn/Fe mass ratio (<3). With the depletion of high grade manganese ore resources, the FeMn ores are becoming important substitution resources for extracting manganese.
Reduction roastingacid leaching process was utilized to process highironcontent manganese oxide ore using black charcoal as reductant. The results indie that, compared with the traditional reductant of anthracite, higher manganese extraction efficiency is achieved at lower roasting temperature and shorter residence time.

found in New Zealand. Worldwide, these deposits are mainly silie ores, with less common carbonate ores, and rare, oxides ores. 1.2. Manganese Alloy The production of manganese alloy from manganese ore is an energy intensive process and therefore, apart from manganese ore, power plays an important role in the production of ese alloy.
The ores are found mixed with earthy impurities like sand, clay, lime stone, etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing. There are several methods for concentrating the ores. The choice of method depends on the nature of the ore.
