Gradually bio-metallurgy technology is becoming an irreplaceable new technology. The nickel-bearing tailings in Jilin, China contains Ni 0.13 %, Cu 0.03%, Co 0.01%, S 15.20%, Fe 6.30%. A comparative study of the HQ0211 bacteria, indigenous bacteria (after the domestication named ZXJE511 bacteria) and acid pool leaching revealed that the local species ore leaching was preferably the best way.

Nickel - Wikipedia

Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium.Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice parameter of ...


The first process that most of the ores or minerals undergo after they leave any mine, is mineral processing or mineral/ ore dressing. It is a process of ore preparation, milling, and ore dressing ...


Spectrographic studies of the ore minerals seem to have been much less popular than the other two approaches from the physical side. The names of but five workers in this part of the field have come to the writer's attention, namely Schneiderhöhn (1929), Claussen (1934), Berthelot and …


Mineral dressing (= Orebeneficiation) The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate ...


Extraction. Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits ). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.


Abstract In this study, magnesia–nickel silicate ore was investigated, which contained 0.83% Ni and antigorite, chlorite, magnetite (Fe3O4), quartz, and mica as the main minerals. Chloride roasting and magnetic separation were used to treat the ore. The addition of red mud enhanced the transformation of nickel silicate to a strongly magnetic mineral mainly comprising metallic Ni and that …


16.2.2 Concentration or Dressing of the Ore Generally, 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 nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores renders them unsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring beneRciation. The usual method of nickel extraction from sulRde


Ten years of research in nickel segregation at MINPRO in Sweden has now reached successful conclusion, after several months of pilot-plant tests in a 1 metric-ton-hour unit. Oxide nickel ore from the Philippines has been calcined and segregated using CaCl2 and coke as additions. Metallic concentrate containing over 60% Ni has been collected by magnetic separation for a total Ni recovery …


The 'mineral dressing' industry (i.e. the concentration of valuable ore materials out of its unavoidable mix with unwanted solids) is a good example of the employment of a very wide range of separation equipment, for use once the mined material has been comminuted to the state where the individual particles are each largely composed of one or ...


Treatments of ores to concentrate their valuable constituents (minerals) into products (concentrate) of smaller bulk, and simultaneously to collect the worthless material (gangue) into discardable waste (tailing), are called as ore dressing/ mineral processing methods. This module explains the methods adopted in mineral processing.


Lithium. Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite LiAl(Si 2 O 5) 2, lepidolite K(Li,Al) 3 (Al,Si,Rb) 4 O 10 (F,OH) 2, spodumene LiAl(SiO 3) 2 and also subsurface brines. Australia and Chile are the world's largest producers of lithium.


Many different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of the rest of this chapter.
