ore grade function and by collecting primary economic and geological data. Methods Data were collected in line with the geographical distribution mine type deposit type and production volumes and total production costs in order to construct cost-cumulative availability curves for platinum group metals PGMs and lithium.

May 11 2017 Factors other than ore grades affect the cost of mineral extraction e.g. mine type new discoveries labour cost and technological developments. Hence minerals other than fossils e.g. metals could be modelled without an ore grade decrease function something that in any case has been heavily criticised by authoritative bodies.

Dec 01 2015 Abstract. This paper assessed the cradle-to-gate life cycle of an iron ore mining. The study was based on production data from an open pit mine located in the Iron QuadrangleBrazil. The functional unit was defined as one tonne of iron ore concentrate produced and the data used were collected directly from the companys production reports .

Environmental geochemistry is an integral part of the mine-life cycle particularly for modern mining. The critical importance of environmental geochemistry begins with pre-mining baseline characterization and the assessment of environmental risks related to mining continues through active mining especially in water and waste management practices and culminates in mine closure.

Life-cycle assessment LCA is a method for assessing the environmental impact of products processes and services. Usually LCA is used to evaluate the total environmental burdens and benefits over the entire life cycle for a product from cradle o grave including material and energy used during extraction and processing of raw materials manufacturing transportation reuse .
