Gold in alluvial gold ore is in the pattern of simple
substance with its big liberation size and blocks/piece/furcation
shape. The diameter is 0.**2mm. Gravity separation-amalgamation
separation can help to get good beneficiation efficiency. The big
blocks of pebbles shall be screened out from the alluvial gold ore,
to avoid damage to the jigger sieves. There are other heavy
materials but the gold in the gold ore, and these heavy materials
can be concentrated as well. There are a lot of blocks of mud-glue
which will be discharged together with the gangue if they are nor
broken down, and this will lead to loss of gold. And here a rotary
screen can make it for both breaking and screening. As a rotary
screening machine, the screen size is usually ****0mm for the
alluvial gold ore.
Gold sand after screening can be put into the gravity
separation, and as the most efficient and most economics placer
gold beneficiation method, gravity separation makes use of density
difference between gold and waste sand by the media of water ( no
other chemicals) without any pollution to environment but with its
high recovery rate. The difference of gold granularity grain size
and also difference of machines' feeding size makes flow sheet of
chute-jigger-shaking table work well with its recovery rate over
*5%. Jiggers of LTA***0/2 and 2LTC***9/8T have been widely used in
the beneficiation of gold alluvial sand, gaining great praises.
The heavy sand from the gravity separation is rich in gold and for
amalgamation, the efficiency will be high. Amalgamation makes use
of the fact that gold can be attracted by mercury alternatively and
then gold is mixed with mercury to form amalgam. Forui Amalgamator
is designed for the placer gold ore. It is easy to operate with its
recovery rate high to over *8%, and also the mercury can be
recycled.
Rotary screen, jiggers, floatation separators, shaking tables,
amalgamators from Forui has been widely used in the beneficiation
of alluvial gold ore. Mini machine test can be done for you free
here in Forui if samples of *0 kgs can be available from you.
