Abstract
A mechanical device for gravimetric concentration of minerals and known as a jig, operating according the known principle and general design thereof, being original in that a continuous and adjustable evacuation of the dense grained fraction occurs in closed compartments which, in this case, are the legs of the mechanical device.
Claims10
Artisanal equipment for concentrating ores, comprising:
- a tank (1) divided into an upper compartment (3) and a lower compartment (4) by a grille (2);
- a device (5) for feeding the upper compartment of the tank with an ore slurry;
- a device (27, 38, 39, 40, 41) for producing upward water pulses through the grille;
- a device (8) for extracting a dense and fine-grained fraction of the ore from the lower compartment of the tank;
- a device for extracting a dense and coarse-grained fraction of the ore from the upper compartment of the tank, this device comprising at least one siphon (10) which is located in the tank and which communicates with at least one opening (12) made in a side wall of the tank, above the grille;
- and
- an overflow (6) for removing a light fraction of the slurry from the upper compartment of the tank, characterized in that said opening (12) in the tank wall discharges into a chamber (20), the upper end of which (21) is located at a higher level than said overflow.
The artisanal equipment as claimed in either of claims 7 and 8, characterized in that the two subchambers (29, 30) of the lower compartment (4) of the tank are prolonged respectively by two hoppers (7) and in that at least part of the membrane-activating member (38) is located between the two hoppers.
