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.
tin processing, preparation of the ore for use in various products.. Tin (Sn) is a relatively soft and ductile metal with a silvery white colour. It has a density of 7.29 grams per cubic centimetre, a low melting point of 231.88 °C (449.38 °F), and a high boiling point of 2,625 °C (4,757 °F). Tin is allotropic; that is, it takes on more than one form.
