Iron ore is the important raw materials of iron and steel production enterprise, natural ore (iron ore) after crushing, grinding, magnetic separation, flotation, re-election and other procedures gradually selected iron. It is a collection of minerals containing iron or iron compounds that can be used economically. The iron ore is converted to Fe3 + after the hydrochloric acid dissolves. Under strong acid conditions, Fe3 + can be reduced to Fe2 + by SnCl2. After the Sn2 + restores the Fe3 +, the methyl orange can also be reduced by Sn2 + reduced to hydrogenated methyl orange, and the methyl orange can instruct Fe3 + to restore the end point.

Technological Process

Stage 1: broken screen breaks - three pieces of closed circuit broken
Large chunks of iron ore deposit are crushed by vibration feeding machine to the jaw crusher or the movable jaw crushing station. After the raw iron ore is sieving, the belt conveyor is sent to the cylinder hydraulic cone crusher. The crushed iron ore is carried into a multi-cylinder hydraulic cone crusher.
Stage 2: grind powder
Will go through sieve sieve 0-12 mm iron powder evenly into the ball mill for grinding, and by the spiral classifier screening, does not conform to the requirements are fed into the ball mill to grind powder;
Stage 3: magnetic selection
The iron powder, which is suitable for selecting ore, is sent to the magnetic separator for strong magnetic and magnetic separation.
Stage 4: drying
The iron powder is then fed into the dryer to dry.
