Glossary

The Metals and Mining industry consists of the location and extraction of mineral reserves, as well as its beneficiation and processing through metallurgical techniques such as smelting, refining and electrolysis, to produce concentrates and refine them into pure metals that satisfy the market's needs.

Activity that consists of reducing the size of previously crushed rocks by pressure or impact, to obtain a suitably low granulometry for the flotation process and the separation of metallic elements of economic interest.

Indicator calculated on mineral reserves and the pace at which they are expected to be extracted. It is expressed in units of time, generally in years.

Ratio between available commercial metal content and the total volume of that metal found in processed ore. It is generally expressed as a percentage (%).

A naturally occurring chemical element or inorganic compound, which has a crystalline structure and characteristic chemical composition. It can be a single element or a combination of multiple ones.

Natural concentration of useful minerals that can be extracted to obtain an economic benefit.

Act by which the State grants a private party the right to explore, exploit and take advantage of the mineral resources present within a defined space and for a specified time, for which the concessionaire pays a consideration.
