C800 Analytical Table

The Laboratory Table or "Super Panner" is an invaluable tool for metallurgists, mineralogists and mill operators analyzing mineral separation. It quickly and efficiently separates mineral grains of close specific gravity.

The separator is supplied with two easily interchangeable stainless steel trays enabling efficient separation over a wide size range.

The 'V' profile tray with 'end knock', when treating closely sized material, is capable of not only of duplicating heavy liquid analysis results, but of giving additional data in the higher SG ranges. The separator is therefore ideally suited to carrying out release analysis.

The 'V' profile tray with 'end knock' is able to accurately predict sand table performance when treating hydraulically classified products. This is of great value in optimization of plant performance.

The flat tray is capable of making very efficient separations of samples finer than 100 microns. This is of value in predicting slime table performance or carrying out release analysis where fineness of the material precludes heavy liquid analysis.

Grade versus Recovery Analysis - Interpretation of test data may be carried out visually, microscopically or by assay analysis of the separated samples. If a complete grade versus recovery evaluation is required, a series of consecutive samples are collected during the separation. At the completion of the run of the product remaining on the tray is then divided into middlings and concentrate to be collected separately. All samples are dried, weighed and the grade versus recovery curve plotted.

'Slime' product from tin plant

Typical separation of a coarse sample on "V" profile tray - a 50 - 100g sample is placed on the tray and wetted. The cylic motion mobilizes the mineral particles enabling stratification to take place. The heavy (usually valuable) mineral settles and is "thrown" upstream by the "end knock" action. The lighter (usually gangue) mineral is carried downstream by the flow of irrigation water to discharge via the tailings launder.

For separation of 100 to 2mm size range.

Sample in slurry form placed on tray.

Partial separation after a few minutes.

Complete separation after several minutes.

Laboratory testing of a fine free gold sample ahead of MGS scoping tests.

Typical separation of a fine sample on a flat tray (without knock) - a 100g sample is dispersed in a beaker of water and poured onto the tray. The cylic motion mobilizes the mineral particles which spread out into a thin layer. Stratification occurs enabling heavy (usually valuable) mineral to sink to the tray surface and be retained. The lighter (usually gangue) mineral is carried downstream by the flow of irrigation water to discharge via the tailings launder.

For separation of 10 - 100 micron samples.
