Mineral Recovering Machine (Patent No: 357632)

Inventor: Gravity Mineral Separator Company Ltd. (assignee)

Location: Calgary

Comments: N/A

Description: What I claim is:

1. In a machine of the class described, comprising a series of inclined sluice tables over which water and debris flow, and an ascending column of water effective at the lower end of said tables to suspend lighter material in said debris and to allow the recoverable heavier material to fall therein; means whereby the debris are subdivided according to size previous to reaching each table, and means to regulate the flow in each ascending column in agreement with the pressure required for the recovery of heavier material with respect to its size.
2. In a machine of the class described, comprising a series of inclined sluice tables adapted to receive the flow of debris and water thereover, and having an ascending column of water at the lower end thereof to suspend lighter materials in said debris and to allow the recoverable heavier material to fall therein; means whereby the debris are subdivided according to size previous to reaching tables succeeding the first, each succeeding table being adapted to a predetermined size, and means to regulate the flow in each ascending column in agreement with the pressure required for the recovery of heavier material with respect to its size.
3. In a machine of the class described, a series of sluice tables adapted to receive debris carried by water thereover and means to cause a current of water to meet said debris and suspend the same to the succeeding table while allowing the heavier recoverable matter to settle in said current, and means to grade the said debris before reaching the tables according to the size adapted to each table, and means to regulate the flow of each current effectively to the size of matter passing over.
4. In a machine of the class described comprising a debris dispensing hopper and a series of metal recovering sluice tables, means to cause said debris to flow to said series of tables comprising an opening around said hopper adapted to admit water therein to carry the debris downwardly through its orifice into said tables.
5. in a machine of the class described comprising a series of sluice tables adapted to receive debris carried by water thereover, means to cause a current of water to meet said debris and suspend the same from one to the succeeding tables while allowing the heavier recoverable matter to settle in said current, and means to grade the said debris according to size after partial recovery and to direct each size to that table adapted to it, and means to regulate the flow of each current in manner effective to the size of matter passing thereover.
6. In a machine of the class described comprising a debris dispensing hopper and a series of metal recovering sluice tables, a water chamber around said hopper, an opening from said chamber to said hopper substantially all around the same and means to supply water to said chamber whereby the debris will be carried downwardly through its orifice into said tables.
7. In a machine of the class described including metal recovering sluice tables and a dispensing hopper adapted to supply debris and water to said tables, a spreading element between said hopper and said tables comprising a pan having vertex to receive the debris from the hopper orifice and lands diverging from said vertex towards its edge to distribute the debris the full width of said tables.
8. In a machine of the class described including a series of mineral recovery sluice tables and a debris dispensing hopper in connection therewith, interchangeable orifice elements removably mounted to said hopper, and means to supply water to said hopper to cause said debris to flow through said orifice to said sluice tables.
9. In a machine of the class described, a series of mineral recovery debris carrying sluice tables, a debris dispensing hopper mounted over one of said tables, a debris spreading element interposed between the orifice of said hopper and said table, an opening around said hopper, a chamber around said opening, means to supply water to said chamber thereby entering said hopper to effect the flow of debris to said spreader and said tables.
10. In a machine of the class described, a main sluice table, an intermediate sluice table and a fine sluice table, water means to deliver metal containing debris to the main sluice table, each of said tables having an incline and means to deliver a current of water upwardly at the lower end of the incline, a controlling gate to gauge the amount of debris passing from the tables over the said means, said means comprising slots across said tables and mineral receivers at the lower end thereof, and sorting means between the main sluice table and the intermediate table and fine table to deliver to each material of intermediate and fine size respectively.
11. In a machine as claimed in claim 10 in which the sluice tables are provided with pebble-like surface.
12. In a machine of the class described, a main sluice table, an intermediate sluice table and a fine sluice table each adapted to recover mineral from debris and water passing thereover, a debris container adapted to feed the main sluice table, a slot at one end of each table, means to cause a water column to flow upwardly of said slots, means to grade the debris according to size comprising parallel bars to receive the debris from the main sluice to eject the coarser matter from the machine, and a screen leading the debris remaining thereon to the intermediate sluice table and that passing therethrough to the fine sluice table, and means to control the flow of said water columns to separate the recoverable mineral by suspending the undesired material thereover and allowing the recoverable to sink therein, according to the grade of the debris.
13. In a machine as claimed in claim 12, an adjustable gate across the sluice tables adjacent the said slots to regulate the amount of debris passing thereunder.
