Canamera and Diamond Indicator Processing grain screening and Heavy Mineral Concentrates (0.25-0.5 mm, 0.5-1.0 mm).



Canamera Geological Services and Diamond Indicator Processing-Heavy mineral separation (sieve, permaroll and magstream) separation and magnetic separation, methylene iodide HMC separation (0.25 - 0.5 mm, 0.5 - 1.0 mm).

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. Samples were screened to obtain the 0.25-0.5 mm fraction. The screened fraction is 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 magnetite 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: (OF 3386 mentions these processes specifically to remove magnetite and micas)

1 Total sample weight (10 kg)
2 0.25 - 0.5 mm sieve split concentrate total wet (kg)
3 0.25 - 0.5 mm sieve concentrate magnetic/paramagnetic separation -non-magnetic/non-paramagnetic split dry (g)
4 0.25 - 0.5 mm sieve concentrate magnetic/paramagnetic separation -magnetic/paramagnetic split dry (g)
5 0.25 - 0.5 mm magnetic/paramagnetic split lights dry (g)
6 0.25 - 0.5 mm magnetic/paramagnetic split heavies dry (g)
7 0.25 - 0.5 mm concentrate examined dry (g)
