The Different Mining Process And Techniques

By buckarunachalam : A how to tutorial about mining courses australia, mining courses online, mining training, education with step by step guide from buckarunachalam.

The process of mining has several steps. The first step is the discovery of an ore body, which involves exploring the extent, location, and value of the ore body. The size and grade of the deposit is then calculated as part of a pre-feasibility study which determines the ore deposits theoretical economics and identifies key risks.

The next step is conducting a feasibility study to evaluate the financial viability, technical, and financial risks of the project. This helps a mining company decide whether to develop the mine or cancel the project. This part also involves mine planning which considers the following: the deposits economically recoverable portion, metallurgy and ore recoverability, marketability of ore concentrates, engineering concerns, milling and infrastructure costs, finance and equity requirements, and an analysis of the proposed mine from the initial excavation.

Access to the ore body starts once it is determined to be worth recovering. The mine buildings and processing plants are constructed and required equipment are gathered. Extracting the ore continues depending on the companys needs. After all the ore has been recovered, reclamation is carried out to make the exploited land usable again.

Mining techniques which one can learn from mining courses Australia have two types: surface mining and sub-surface or underground mining. Surface mining yields most of the minerals except for petroleum, natural gas, and metallic ores. It uses in-situ leaching, a technique that involves extracting soluble minerals such as potash, potassium chloride, sodium chloride, and sodium sulfate.

As part of surface mining training courses, one would experience removing surface vegetation, dirt, and layers of bedrock to extract buried ore deposits. Other mining techniques one can learn are open-pit and strip mining. Open-pit mining recovers materials from an open pit in the ground, while strip mining involves stripping surface layers off to reveal ore.

Taking mining courses online will familiarize you about another important type of mining: sub-surface mining. Sub-surface mining involves digging tunnels into the earth to extract ore deposits. It implements drift mining technique which uses horizontal access tunnels and slope mining for diagonally, sloping access shafts and shaft mining for vertical access shafts.
