Whats an ore
Ore means that a mineral or an aggregate of minerals from which an invaluable constituent, especially a metal, may be profitably mined or extracted. An ore can be a material that contains metallic such quantities that it may be mined and worked commercially to extract that metal. The metal is normally contained in chemical in conjunction with another element in addition to varied impurities.
Ore mineral could be classified in different contents the following.
1. By ore minerals are helpful in industrial performance ore may be split into metal ores (for example iron ore, copper ore, molybdenum ore, bauxite ore, platinum ore, zinc ore, cobalt ore, silver ore, gold ore, nickel ore, titanium ore, tungsten ore, platinum ore, tin ore, uranium ore, etc.) and non-metallic minerals (e.g. fluorite ore, asbestos ore, lead ore, etc.).
2. By ore useful minerals or metals included in the number of elements ore could be divided into simple minerals (for example tungsten ores, mercury ores, etc.) and integrated mineral (including Pb-Zn, W-Sn ore, etc.)
3. By mineral content with the useful components it may be split into poor ores (such as poor banded magnetite ore, iron 30%) and rich ores (compact massive magnetite ores, iron 60%).
4. According to the structure of ore it can be divided into dense massive ore, disseminated ore, banded ore, breccias ore, etc.
5. By mineral weathering it can be split up into different amounts of primary ore, oxide ore and mixed ore.
Ore carrier: ore deposits
An ore deposit is an accumulation of ore. This is distinct from the mineral resource as defined by the mineral resource classification criteria. An ore deposit is one occurrence with the particular ore type.
There are numerous kinds of deposits. Solid deposits will be in the widest distribution, liquid deposits include liquid petroleum deposits, hot brine and groundwater, and gas deposits are natural gas.
The basic extraction of ore deposits follows the steps below
1. Prospecting or exploration to discover after which define the extent and price of ore where it is located (“ore body”)
2. Conduct resource estimation to mathematically estimate the size and grade from the deposit
3. Conduct a pre-feasibility study to discover the theoretical economics from 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 from the project making a decision as whether or not to develop or avoid a proposed mine project. This includes mine likely to evaluate the economically recoverable percentage of the deposit, the metallurgy and ore recoverability, marketability and playability of the ore concentrates, engineering, milling and infrastructure costs, finance and equity requirements plus a cradle to grave research into the possible mine, from your initial excavation completely to reclamation.
5. Development to produce use of an ore body and building of mine plant and equipment
6. The operation of the mine in an active sense
7. Reclamation to create land the place where a mine had been suited to future use
