  • Brief introductions for Placer Gold Concentrator

    Placer  Gold contains a number of heavy minerals in addition to gold  and is commonly associated  with magnetite ,ilmenite, rutile, zirconium  quartz, hematite, ferrochrome, iridium, cinnabar, tungsten, manganese, tin,  diamond, corundum, calcite and  other heavy minerals with its content being  1-3ktg/m3 as well as  gravel, cobble and soil. Presence of soil is not  favorable for recovering fine  gold in the process of gold dressing.

    Efforts  should be made to conduct  crushing, screening and desliming operations in the period of separation.  Consideration should be given to comprehensively  recovering the heavy metal  elements with desirable indexes available.  

    Normally, placer gold occurs in granular, flaky, branched and needle shapes  with 0.3-10g/t in grade and 0.2-2mm  in size, Preference should be give to  gravity concentration in ore dressing.  

    Also, consideration should be given  to comprehensively recovering other heavy  minerals by combined use of  gravity, flotation, amalgamation, magnetic separation  processes to separate  minerals.

     

     

    Placer Gold Concentrator for processing placer gold

    Placer gold dressing equipment and process are available in a number of types:  centrifugal  separator, cone separator and jig complete with spiral chute,  table, stationary chute, vibrating chute and others.

    Feedbacks  from customers for the equipment application over  years show that relatively  stable in ore dressing is to introduce placer  gold two-layer combined chute  with large production capacity , low costs.  less use of land , mountingability  and dismountingability, removability.  Recovery rate for roughing is 80 – 85%  and recovery rate for cleaning 90 – 95%.

     


    Placer Gold Concentrator Production  Process

    Run-of-mine placer gold is hauled by bulldozer and excavatorinto  screening machine for breaking, classification and desliming prior to being  delivered into ore box of chute, where placer gold is flushed with a large  quantityof high pressure water and after being subject to full washing, slurry  will flow  into sieve-mesh plate and a fraction of 20 – 60 mm size of ore is fed into  intermediate  cell of the chute for processing.  

    Undersize  product with a fraction of ≤20mm placer is distributed to   the chutes at two sides of the lower layer with the chute bottom provided  with  lattice bar and felt mat. When slurry flows through the lattice bar and  the  felt mat, stratification is performed in density and grain size.

    Gold  grain and  heavy minerals are concentrated on the felt mat and the chute is  provided with  theftproof door lock. When a shift is changed for cleaning the  felt, the lock  will be opened by an assigned person.

    The concentrate cleaned  out is transferred  into the vibrating chute for cleaning and placer gold and  other heavy minerals  are separated out using table before being subject to  chemical treatment for  delivery to smelting furnace for production.
