Mining of Iron Ores – IspatGuru
The process of mining consists of discovery of an iron ore deposit through extraction of iron ore and finally to returning the land to its natural state. It consists of several distinct steps. The first is discovery of the iron ore deposit which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body. This leads to a mathematical

Metal ore mining in Europe
About 83 % of their iron ore goes into the processing and production of pellets. However, in 2014 and 2015, the company‘s operational result collapsed due to iron ore price erosion, and the company went into the red. It had to implement measures to cut costs and increase productivity. In the meantime, the situation has improved and LKAB is now seeking to expand its production capacity.

Ore processing – Waihi Gold
Ore processing is a 24 hour operation. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process
