GOLD CONCENTRATOR,
GOLD SEPARATOR, CENTRIFUGAL CONCENTRATOR

DOVE Gold Concentrator is highly efficient gold separator, designed for highest ratio of fine gold and other heavy minerals recovery. DOVE Centrifugal Gold Concentrator is a type of Gravity separation device, designed for 100% separation and recovery of free Gold, Silver and Platinum group of metals, replacing Amalgamation and use of Mercury.

DOVE Gold Concentrator is economical and efficient gold separator for recovery of Placer (Alluvial) Gold, Hard Rock Gold and Gold and other heavy minerals from old tailings. It is environment-friendly, requires no chemicals, additives or regents, utilize only water.

It is a highly effective device for high concentration ratio and high recovery of Coarse (7.0 – 2.0 mm), Fine (2 – 0.6 mm), and Ultrafine (0.60 – 0.04 mm)  Gold, Platinum  group of metals and other heavy mineral particles. It uses the Gravity concept combined with high speed rotation to generate “G” force, which can result in separation and recovery of Coarse, Fine and Ultrafine Gold and other minerals particles, less than 40 microns.

OPERATING PRINCIPALS:

DOVE Centrifugal Gold Concentrator is based on the principal of Centrifuge force and gravity to enhance the gravitational force applied to solid particles in the slurry feed and to effect the separation of solid particles based on particles density. The main component in the DOVE Concentrator is a cone shaped bowl. The surface of the Concentrating Bowl is designed with series of Ribs (Riffles) and between each pair of Ribs is a Groove. The concentrating bowl rotates at high speed by an electric motor and the pressurized feed is introduced in the form of slurry into the concentrating bowl from the bottom of the bowl through a central feed pipe.

The concentrating bowl rotates at high speed and a centrifugal force of (60 G) causes the slurry feed solids to separate from the water and fill the Grooves between the riffles, from the bottom of the concentrating bowl to the top of the bowl.

As the pressurized slurry feed continues entering the bowl the process of settlement of solids based on gravitational force takes place, where the heavier minerals particles displaces the lighter minerals particles which was trapped in the Grooves. The continues replacement of heavier particles will result in the light particles to be carried by the water to the top of the concentrating bowl and to the reject channel.

DOVE Concentrating Bowl is designed with multiple Fluidization holes inside the Groove of the Concentrating Bowl. The purpose of these microscopic holes are to fluidized the Groove by introducing water through this holes. This fluidization process shall result in inhabiting sever compaction of the heavy minerals settled inside the Groove, due to the powerful centrifugal force.
