8.2: Mining and Ore Processing

Relatively deep deposits, or those with elongated or irregular shapes are typically mined from underground with deep vertical shafts, declines (sloped tunnels) and levels (horizontal tunnels) (Figures 8.2.1 and 8.2.2).

Mining

The openings made in the process of extracting ore are called stopes or rooms. There are two steps involved in stoping. The first is development—that is, preparing the ore blocks for mining—and the second is production, or stoping, itself. Ore development is generally much more expensive on a per-ton basis than stoping, so that every effort ...

Steel Making Process – Complete Overview with Flowchart

Let's understand the Steel making process steps in detail. 1. The Bessemer Process. The Bessemer steel making process consists of blowing air through molten pig iron contained in a special furnace known as a converter which shaped like a huge concrete mixer (Fig. 4.2). The converter is made of steel plates lined inside with a refractory material.

Boron Mining: Sources And Major Producers | Borates Today

The next step is separating the minerals from each other using large pieces of equipment called crushing mills or grinding machines. Finally, you get a low-grade Borax product with an estimated 40% purity level. This Borax is then processed to create a white powder and later sold to Borax buyers. The process of Boron mining is around for years ...

Steel production process: what are the steps?

Step 1: Cargo preparation. In the steel industry, the raw material for steel production is iron ore. And in the first stage of the production process for this material, iron ore is agglomerated using lime and coke fines. At the end of this step, the resulting product is called sinter. The charcoal used is processed in the coke oven plant and ...
