Introduction: Jig concentrator (jig separator, jig machine) is a equipment that drives pulses of water upwards through a thick bed of settled sediment to keep it loose and agitated.This achieves gravitational separation by allowing the denser minerals to sink easily and quickly through the lighter minerals. A typical jig consists of a water-filled tank known as a jig-cell, …

Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.

Molecular sieve adsorbents are crystalline aluminosilicates, known as zeolites. Their unique structure allows the water of crystallization to be removed, leaving a porous crystalline structure. These pores, or cages, have a high affinity to re-adsorb water or other polar molecules. Aided by strong ionic forces (electrostatic fields) due to the ...

sample is then weighed and sieved through a 0,425 mm sieve. It is desirable to place a 2.00 mm or a 4,75 mm sieve above the 0,425 mm sieve to act as a guard for the finer sieve. The material retained on the 0,425 mm sieve is transferred to a mortar and by rubbing with a rubber-tipped pestle, most of the soil aggregations are disintegrated
