Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel.

then reacts with the iron ore to form carbon dioxide and pure iron. Separating the iron from the slag 2 The melted iron sinks to the bottom of the furnace. The limestone combines with the rock and other impurities in the ore to form a slag which is lighter than the iron and floats on top.

Crushing and grinding: The crushing of ores into a fine powder in a crusher or ball mill is the first step of Metallurgy. 2. The concentration of ores: The next process of Metallurgy to separate impurities from ore is known as a concentration of minerals or ore dressing.

Jun 30, 2021 · First the ore goes into autogenous grinding mills and then ball mills, where the crushing process continues until it's a fine powder. At intervals in the crushing process, magnetic separation draws the valuable magnetite concentrate away from waste.

The ore processing facility (OPF) at Firetail will process bedded iron ore for the first two years of mining. The deposits will be dryprocessed for the direct shipping of ore. The ore is crushed in the primary crushing hub and transported back to the OPFs for grinding and separation.
