1．General

CGLC60A Combined Placer Gold Separation  Chute is designed and manufactured by assimilating advantages of the advanced  structure on the basis of American chute imported by our factory and Longjiang  1 Model Chute in      China.  It also has undergone many production tests and improvements with its  advantages as follows:

A．Large  capacity of handling placer gold at a washing capacity of 60    -80m³/h.

B．Rational  structure, high strength, removable and easy to be transported and transferred.

C．High  recovery in gold mining at a rate of 75-80%, recovering not only granular gold  and platelet gold but particulate gold.

D．Strong  adaptability and applicable for beneficiation of ore deposits at any  conditions.

2．Technical Data Placer Gold Separation Sluice

3．Main Structure and Function of Chute

A．Feeding  platform - section of carrying gold placer materials and place where pulp is  fully produced.

B．Screening  device – composed of screen plate and separation box.

C．Chute –  including primary chute and secondary chute with the primary chute put in place  in middle and the secondary chute on both sides; major part of gold mining and  separation.

D．Chute –  including primary chute and secondary chute with the former housing 9 lattices  and the latter containing 11 lattices on every side.

E．Base – made  up of 4 ground beams and 11 cross beams, which are mounted on the base in  order, forming a complete chute.

F．Main water  spraying pipe – water source device for gold mining and separation, composed of    12 in flow blending pump for  water supply which is mounted above inclined screen plate.

G．Secondary  water spraying pipe – replenishing water volume for the primary water spraying  pipe and expanding area of water spraying, connecting with the primary water  spray by linking    6 in rubber  pipe at its end; mounted above the square screen plate.

H．Plastic  felt – covered at the bottoms of the primary and secondary chutes, a main area  for storing placer gold.

I．Electrical  device – driven by either diesel engine or electrical generator; If electric  circuit is available in the area, electrical motor can be used for operation.

J．Auxiliary  equipment: placer gold separator and gold placer box.

4．Installation and commissioning

After the position of installation is  selected, stripped waste rock will be pushed by bulldozer to form slope  foundation with dip angle 100~120, 14 meters in length and 5 meters in width.  6~8 pieces of timber sleeper are put on the foundation and then leveled. The  chute will be assembled on the foundation according to sequences. Each  connecting points will be connected with bolts. All bolts must be tightened.  The installation angle of chute will be determined according to the size and  shape of placer gold particles. The slope of chute should be slightly large,  when platelet gold or large and medium particles of placer gold are dominant.  The slope of chute should be slightly small, when the platelet and particulate  gold and small particles of placer gold are dominant to ensure recovery. After  the angle of the chute is determined, the position of the chute will be  adjusted.

Water pump should be installed on the  position selected, and connected to form return circuit with rubber hose.

Power line and electric operating equipment  should be installed properly.

When everything is ready, power supply and  water pump will be connected to conduct chute beneficiation experiment. If the  experiment is successful, the chute can be used in production. The chute should  be cleaned every 8 hours. Before cleaning, feeding should be stopped, and water  should be supplied continuously. After cleaning 5~10 minutes, the supply of  water should be stopped. Main and auxiliary chute lattices are taken out, and  floating sands on the hair felt are collected to the gold sand tank before  rolling up the hair felt and putting it into the gold tank for vibrating and  washing . After being cleaned, the hair felt is put back into the chute, and is  used to produce gold placer again. The gold sand in the gold placer tank will  be sent with spade to cleaning machine to product cleaning. Then gold placer  will be produced via manual fine elutriation.

5．Important for chute operation

A．The plates  of feeding platform, primary chute and secondary chute are welded with steel   plate and should be protected from collision to avoid deformation during  material supply, feeding tailing and transport.

B．During  washing, adequacy water in primary chute and secondary chute should be ensured  at rated capacity and adjustment of pump should be done timely in case of shortage  of water supply. Generally solid-liquid ratio of slurry in the chute is  10~12:1, flow velocity is 1.4~    1.6 m/s.  Lateral of chute should be kept level.

C．Screen  plate of the chute is used for screening placer gold. When screen holes are  blocked, it should be cleaned timely.

D．In washing,  cleaning time of chute is determined according to actual situation. If gold  grain is bigger, a cleaning chute per 8~10 h., if gold grain is small or platelet  gold, a cleaning chute per 6~8 h.

E．In moving  chute for long distance, disassembly moving should be done, assembly on new  base should be according to previous installation sequence, jointing bolt must  be tightened. If chute is moved in whole unit, drawbar must be used, passing  hole in two ends of ground beam, other part of chute can be not drawn.
