Below are the details of the customer’s gold mine project
Alluvial gold with much sticky clay
Raw materials mix big stones, 150-250mm
Gold size range 0-12mm
Process capacity 200tons per hour
The flowchart designed based on the gold mine details
200TPH Clay Alluvial Gold Wash Plant Main machines as below
vibration feeder
Trommel drum
High-frequency vibration screen
Gold sluice box
Belt conveyor
Brief introduction for the flowchart
the materials will lead to the vibration feeder by truck or excavator as the customer wants, then feeder to the trommel scrubber to wash the sticky clay, output from the trommel scrubber will to the high-frequency vibration screen to separate the gold size 0-6mm and 6-12mm to the gold sluice box to get the gold concentrate, big waste stones +12mm will transport by the belt conveyor.
FAQ about the gold processing flowsheet
how to remove the sticky clay in the raw materials?
Answer: the trommel scrubber is used for washing the sticky clay, when it works, will continue rotary with water, the sticky clay will hit and spread in the water.
There are two types of lining of the trommel scrubber
Rubber lining: easy to change and install, can be used for 1-2years
Manganese steel: not convenient to change and install, but much cheaper than the rubber lining,can be used 3-6 months
how to remove the big stones?
Answer: The feeding size of the trommel scrubber is 0-75mm, there have 150-250mm big stones in the raw material, so we add the vibration feeder with the grizzly bar before the trommel scrubber, the sieve of the grizzly bar will be made of 75mm, 0-75mm will to the trommel scrubber, +75mm will to the waste pile.
how to get the gold?
Answer: The gold size range is 0-12mm, we add two sets of high-frequency vibration screens after the trommel scrubber, one set for separating the size 0-6mm materials, another set for separating the size 6-12mm materials.
The 0-6mm and 6-12mm will to the gold sluice box to get the gold concentrate.
two sets sluice box for each vibration screen, the additional sluice box is for recovering the tailing of the sluice box after the vibration screen.
how much water will need for the machines?
Answer: the water consumption for the raw materials is 3:1, which means 3m³ water will need for 1ton raw materials. enough water will make sure to clean the sticky clay.
how do choose suitable generators for the machines?
Answer: add the total power of the machines, then multiply by 1.35, that’s the actual generator will need.
