The Spiral Concentrator Lg7, A New Concept For The Recuperation of Fine Gold
Description of the Spiral Concentrators
In a certain manner, the spiral term is used wrongly for identifying the concentrator LG7, because the characteristics of the design and function of the unit are completely different to those of the conventional spirals, for example, the Humphreys which was invented by I.B. Humphreys in 1943. for something of around 35 years, all the produced spirals for concentration of minerals have incorporated doors for the remotion of products located in each turn of the spiral canal; the metallurgical control located through the adjustment of each door to control the degree and the amount of the products removed from the canal for the pulp. The water for cleaning (or water of washing) was added to the canal of spiral at the length of all the spiral canal with the object of increasing the remotion of the gangue of the concentrated product. The spacing was fixed (the vertical distance among the turns) and the surroundings (or the profile of the canal) was constant through the whole canal of spiral. The optimal metallurgic efficiency, in general was limited to minerals within the gama of sizes of approximately net 14 to net 150.
The Reichert spiral LG7 incorporates concepts which simplify the control of the spiral and increase the metallurgical efficiency in comparison with other spirals. The LG7 is equipped with only one set of distributors of the products, located in the point of unloading of the canal, this unloading of the concentrate, intermediate components (middlings, wastes and a fraction of water is effectuated in separate forms).
