Blue Bowl
Methods to Clean Your Concentrates
The gravimetric concentrator provides a concentrate which requires final cleaning or upgrading. Common methods include:
Table / Blue Bowl
Tables and bowls have been proven to be very effective for final cleaning. They are slow but very clean. They use no chemicals are safe for the environment and your family. They are fun and provide immediate gratification – after each cleanup you will see high grade gold. ICON is proud to recommend the Blue Bowl for small volume final cleanups.
Regional Processing
Regional processing is becoming more common around the world. Miners are using ICON at their site and transporting a small volume of concentrate to regional processing plants. This is becoming the method of choice where hard rock miners have learned the value of their tails and are using the ICON to pre-concentrate the sulfides or entrapped gold. You may be able to reduce your ore to 2 to 3% and concentrate the entrapped sulfide gold.
Cyanide Leaching
This is the recommended method of the Global Mercury Program. Without pre-concentration the volume of material to treat and the amount of chemicals are tremendous. Concentration allows the operator to treat a reasonable amount of material either on site or at regional facilities serving many mines.
Mercury Amalgamation
This is not recommended due to the environmental impacts and the effectiveness of the blue bowl and/or tables. When practicing ‘whole ore amalgamation’ a miner will place mercury directly into the ball mill. In this case 100% of the ore is exposed to mercury. When a concentrator is used the amount of ore can be reduced dramatically to a small amount of concentrate. 1 ton (1000 kg) of ore could be reduced to 1 kg of concentrate. If the miner chooses to amalgamate the concentrate only a fraction of the mercury would be used and only a small percentage of the ore would be exposed to Hg.
The ICON process allows an operator to either amalgamate, table or bowl a reasonable quantity.
