· 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 …

The force experienced in the magnetic field is given by the equation f=m/k.H.dh/dx. with k=magnetic susceptibility, H-magnetic field strength, and dh/dx being the magnetic field gradient. As seen in this equation, the separation can be driven in two ways, either through a gradient in a magnetic field or the strength of a magnetic field.

There are many methods of separation (concentration) of minerals: 1) Gravity separation. There are more than 12 types of gravity separation of minerals. It is used for the extraction of gold, coal, cassiterite, wolframite, rare earth mineral, niobium, zirconium, uranium minerals, and others. Read more . 2) Magnetic separation. There are more than 14 types of magnetic separation of minerals.

· concentration of ore (1) hydraulic washing (2) magnetic separation (3) froth floatation method (4) leaching explain in short from - Chemistry - General Principles and Processes of Isolation of …

In this method of Magnetic Separation, we use the magnetic properties of certain metals to divide them from the non-magnetic gangue. Here we place the powdered ore on a roller belt. One belt of this roller is a magnet. So the magnetic material attracts to the metal belt and stays on the belt. The non-magnetic gangue falls in a heap from the belt.

· The adjustment of pulp concentration needs to be determined according to the specific situation. 2. Effect of ore particle size on magnetic separator. The size of ore feed size of magnetic separator is an important factor that affects the magnetic separation effect of magnetic separator. If the ore particle size is larger or coarser, it ...

Some of the common methods of ore concentration are discussed below. 1. Gravity separation or Hydraulic wash. In this method, the ore having high specific gravity is separated from the gangue that has low specific gravity by simply washing with running water. Ore is crushed to a finely powdered form and treated with rapidly flowing current of ...

Magnetic separation can be useful especially in mining iron as it is separated by a magnet. (Mineral Technologies, 2016) 2.3.1 Applications of Magnetic Separation Wet High Intensity Magnetic Separator (WHIMS) • From mineral sands, recovery of ilmenite, chromite and monazite uses this machine.

The lower limit size of the use of gravity separation to date is 5 microns. Major losses in golden gravity separation comprise splices of gold with other minerals, platelet-shaped particles of gold, micro and nanoparticles of gold. Recovery of gold of size of 50-100 microns is 96 %. Flotation separation.

There are numerous methods of concentration and the methods are chosen based on the properties of the ore. Hydraulic Washing: This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore. This is a type of gravity separation. Magnetic ...

This method of separation is used when either the ore particles or the gangue associated with it possess magnetic properties. For example, chromite Fe(CrO 2) 2 being magnetic can be separated from the non-magnetic silicious gangue by magnetic separation.. This method is widely used for the separation of two minerals, when one of them happens to be magnetic.
