Ore What’s an ore ?

Ore means that a mineral or an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined or extracted. An ore is a material that contains a metal in such quantities that it can be mined and worked commercially to extract that metal. The metal is usually contained in chemical combination with some other element in addition to various impurities.

Ore classification

Ore mineral can be classified in different contents as follows.

1. By ore minerals are useful in industrial performance ore can be divided into metal ores (such as 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 contained in the number of elements ore can be divided into simple minerals (such as tungsten ores, mercury ores, etc.) and integrated mineral (such as Pb-Zn, W-Sn ore, etc.)

3. By mineral content of the useful components it can be divided 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 divided into different levels of primary ore, oxide ore and mixed ore.

Ore carrier: ore deposits

An ore deposit is an accumulation of ore. This is distinct from a mineral resource as defined by the mineral resource classification criteria. An ore deposit is one occurrence of the particular ore type.

There are many types of deposits. Solid deposits are 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 find and then define the extent and value of ore where it is located ('ore body')

Conduct resource estimation to mathematically estimate the size and grade of the deposit

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.

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 playability 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.

Development to create access to an ore body and building of mine plant and equipment

The operation of the mine in an active sense

Reclamation to make land where a mine had been suitable for future use
