Comminution tests (ball mill grindability) returned average Bond Work Index (BWI) values that categorize MET-1 as medium and MET-2 as moderately soft. More testwork will be undertaken to improve the 24- to 48-hour gold recoveries and optimize the leach residence time. Improvements are expected with these tests.

The Bond Ball Mill Work index (BBWi) is the industry standard procedure for assessing the grindability of ores. The test involves conducting a locked-cycle grinding test using Bond's standard mill design. The locked-cycle test enables a batch process to emulate the grinding behaviour of a continuous mill with a 250% recirculating load.

Bond work index of ball mill. In this paper, the standard Bond method was used to measure the Bond work index (W i) by ball milling to estimate the grindability of Indian hematite fines [11,12,13]. In addition, W i of a common hematite fine widely used in steels, namely BHC, was also determined as a comparison value.
A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s). Sample requirements: A minimum of 8 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm, as required for the Bond Ball Mill Work Index test feed.
