Amenability testing is the initial test phase that evaluates the compatibility of the BioHeap bacterial cultures to a particular ore. During this phase a culture is adapted to the particular ore and a range of diagnostic tests, including head assay, mineralogy, acid consumption and crush size optimization (referred to as a NAD test) is performed.

BioHeap have standard procedures and reporting procedures well developed for this phase of testwork, and it is performed as a fixed price service. This phase of testwork provides a report and a simple design criteria that estimates a number of key design elements. A simple cashflow model can be generated from this phase of testwork.

Amenability testing is available in house at BioHeap’s laboratory in Waterford, Western Australia. This testing phase takes 16 weeks and requires 30kg of ore.
