AGQ Labs to keep environmental tabs on Glencore’s Contonga polymetallic mine
AGQ Labs’ mining division has been awarded a contract to
carry out the environmental monitoring of the quality of soil, water, plant and
hydrobiological tissue at Glencore’s Contonga polymetallic mine, in Peru.
The Contonga mine, in Ancash, is owned by Glencore
subsidiary Compañía Minera Los Quenuales. It is a polymetallic underground
zinc, lead, copper and silver mine with more than 100 years of operating
history, according to AGQ Labs. Glencore acquired the asset from Nyrstar back
in September 2017.
The mining company, as part of its environmental commitment
at the mine, performs environmental monitoring of its components to determine
their chemical stability and the potential for acid mine generation, as well as
their characterisation through complementary studies, AGQ Labs said.
AGQ Labs Mining will provide the sampling service and
technical analytical support through a specialised service for the
characterisation of soils, waters and plant tissue. This uses selective
analytical techniques for the characterisation of the matrices under study.
For this, AGQ Labs uses a set of tests to define the quality
of the soils under study through fertility tests and characterisation of the
profiles.
Mobilisation of the different analytes under study are also
characterised through leaching tests such as methodologies proposed by Tessier
and the Flask Extraction Test. The characterisation of its acid generation
capacity with ABA methodologies and mineralogy analysis is carried out with
Thin Sheet Microscopy.
AGQ Labs said: “The characterisation works are complemented
by the taxonomic classification of the most representative flora and the study
of the waters through laboratory analyses of physicochemical and
hydrobiological parameters.”
