Laboratory Mineral Separator Table

Rapid separation of mineral grains for mineralogists, metallurgists and mill operators. The 911C800 Laboratory Mineral Separator is a valuable tool for metallurgists, mineralogists and mill operators. It quickly and efficiently separates mineral grains of close specific gravity.
The Superpanner is a Mechanism invented by Professor H. T. Haultain which simulates rocking,bumping, and sluicing action used in panning, and gives precise information as to possibility of gravity treatment of sands. Used in rapid assays and as a research aid.
Tabling tests can begin with individual treatment of each size from about 50 mesh down to, say, 20um on a Haultain superpanner. If material can be concentrated by gravity methods (tabling, vanning, and spiralling included), it can be concentrated on a superpanner. If this instrument fails, no commercial method will succeed on fine sizes. The super-panner is a miniature shaking table into which are built most, if not all, of the motions used in panning. A sample of a few grams can be tested, or some hundreds of grams can be worked in successive additions and particle removals. There is, in fact, no great virtue in using more than a light charge when testing for a gravity process, but bigger quantities are treated when search is being made for particles of heavy minerals only present in very small amounts. The advantage to the microscopist of being able to examine a sample of, say, half a gram which should contain all the heavier minerals from a total of half a kilogram are obvious. Any desired texture of decking can be used on the superpanner, linoleum and stainless steel being sufficient for most work. Adjustments are for side and end shake. slope, bump, stroke length and speed, and sluicing water.
A most effective instrument and it has always been a puzzle to me that it is not been universally used by millmen.
