AGQ Labs has won a contract to carry out environmental sample analysis services for Minera Chinalco Perú SA over the next three years.
Minera Chinalco owns the Toromocho open-pit copper mine in the Morococha district of Peru, situated 4,500 m above sea level. Toromocho will produce 1 Mt/y of copper concentrate, 10,000 t/y of molybdenum and 4 Moz/y of silver oxide, according to the company’s website.
Minera Chinalco is a subsidiary of Aluminum Corporation of China, the second largest alumina producer in the world and the third largest producer of primary aluminium.
The purpose of the AGQ Labs contract is to analyse environmental samples during the next three years in various environmental matrices, including:
- Surface waters, in this matrix, will be determined in accordance with the environmental quality standards (ECAs), looking at, among other parameters, run of total metals, anions, cyanide, microbiological and hydrobiological, volatile organic compounds, semi-volatile, organochlorine pesticides, phosphors, carbamates and polychlorinated biphenyls;
- Groundwater, among other parameters, will be analysed for metals, anions, cyanides, COD, microbiological elements;
- Domestic and industrial wastewater, in accordance with the applicable legislation for the sector, will be analysed for, among other parameters, metals, anions, cyanides, coliforms, etc;
- Drinking water, complying with 100% of DS 031-2010.SA, will be looked at for microbiological and parasitological, organoleptic, volatile, semi-volatile organic compounds, pesticides and alpha and beta radiation;
- Air quality will be determined according to the applicable ECAs, among others PM10, PM2.5 particulate material, metals, gases and others;
- Characterisation of soils – cover or top soil – where the study of agronomic characterisation, metal run, and others of relevance for the purpose will be made;
- Soils and sediments, in order to verify compliance with the applicable ECAs, will be analysed for metal, hydrocarbons in the three fractions, volatile and semi-volatile organic compounds, and other elements;
- For environmental geochemistry, an ABA Test, and others will be determined;
- Characterisation of mining waste, applying the current standard in accordance with the EPA standard and others, for flammability, corrosivity, reactivity, toxicity and pathogenicity. According to the test results, a judgment will be issued about the associated risk; and
- Environmental monitoring of air quality parameters, electromagnetic radiation and day and night environmental noise will be examined in accordance with current regulations.
In this sense, Minera Chinalco is entrusting to AGQ Labs a specialised service for the monitoring and analysis of environmental samples, according to its experience and national accreditation, the company said.
