Ore is playing an important role in our life, I cant't think the life if there is no ore. Ore is a mineral or an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted. What usually used in our life are iron, copper, aluminium. In order to get this metal, we must make ore processing.
The first step usually is ore crushing process. We use ore crusher to crush these ore into small pieces.
Usually we use a complete crushing plant to crush, thus the small ores can meet our requirements. Then we must grind the small pieces into powder in ore milling preocess. The basic extraction of ore deposits follows the steps below;
1. Prospecting or Exploration to find and then define the extent and value of ore where it is located ("ore body")
2. Conduct resource estimation to mathematically estimate the size and grade of the deposit 3. Conduct a pre-feasibility study to determine the theoretical economics of the ore deposit. This identifies, early on, whether further investment in estimation and engineering studies is warranted and identifies key risks and areas for further work.
4. Conduct a feasibility study to evaluate the financial viability, technical and financial risks and robustness of the project and make a decision as whether to develop or walk away from a proposed mine project. This includes mine planning to evaluate the economically recoverable portion of the deposit, the metallurgy and ore recoverability, marketability and payability of the ore concentrates, engineering, milling and infrastructure costs, finance and equity requirements and a cradle to grave analysis of the possible mine, from the initial excavation all the way through to reclamation.
5. Development to create access to an ore body and building of mine plant and equipment 6. The operation of the mine in an active sense
7. Reclamation to make land where a mine had been suitable for future use
