PARTIAL-LEACH EXPLORATION GEOCHEMISTRY
Partial Leach approaches are used where it is desired for metals to be extracted from surface coatings of soil grains, without dissolving the underlying host matrix. Metals adsorbed onto these outer layers or held in metallic oxide coatings on soil grains have been mobilised through the soil profile, and can give good indications of orebodies deep under cover. Different leaches apply to different soil types, with some being more specific than others. Please call Brad or Andrew to discuss the appropriate leach for your application and arrange an orientation study if required.
Partial-Leach Extraction
Our partial leach extractions cover most requirements, from very benign (water leach), through broad-spectrum chelating (PL-01) to aggressive (aqua- regia). Other leaches are available on request.
