The six main steps of iron ore processing
When iron ore is extracted from a mine, it must undergo several processing stages. 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.

Fundamental studies for high temperature processing of tungsten
The first step in the production of tungsten is to enrich tungsten from two minerals wolframite ((Fe, Mn)WO4) and scheelite (CaWO4) through the leaching process. The leaching residue usually contains a certain amount (2–5 wt%) of WO3 which is higher than that in the tungsten ore (generally less than 1 wt%). In addition, the leaching …
