Canamera grain screening and Heavy Mineral Concentrates (0.25-0.5 mm, 0.5-0.84 mm, 0.84–2.00 mm)



Canamera Geological Services, Heavy Mineral Processing -Heavy mineral separation (sieve, permaroll and magstream) separation (0.25 - 0.5 mm, 0.5 - 0.84 mm, 0.84 – 2.00 mm) of kimberlite sample.

General Methodology:

Canamera Geological Ltd North Vancouver, BC . and Diamond Indicator Processing of Thunder Bay Ontario Mineral grain screening and Heavy Mineral Concentrations (HMC) using Permaroll and Magstream separation methods. Sample is disaggregated and is screened to obtain the 0.25-0.5 mm, 0.5-0.84 mm and 0.84 – 2.0 mm fractions. Screened fractions are magnetically separated by Permaroll separator and minerals are separated into heavy and light fractions using a Magstream separator. Samples are then sent to Diamond Indicator Minerals Processing for magnetic grain separation and Heavy Mineral Concentration (HMC) specifically to remove hornblende and micas. Samples are run through a magnetic separator and run through methylene iodide diluted with acetone (specific gravity =3.2). Numerous weights are recorded during the procedure, as listed in the table below: Weight data for the 0.25-0.50 mm fraction is included in the Open File report OF 3924 while weight data for the 0.5-0.84 mm and 0.84-2.00mm fraction is missing. (OF 3924 mentions these processes specifically to remove hornblende and micas)
