Gold Ore Processing Methods Used in Zimbabwe
Gold ore extracted by miners is transported to the custom milling centers to be ground and concentrated by operators. The custom milling centers are a desirable solution as this organizes the activity and avoids the use of mercury in different places. However, the millers allow miners (customers) to use their own mercury at any step of the process.
The technology employed by the custom milling centers varies. For crushing and grinding, some of them use wet stamp mills (3 or 5 stamps) with capacity of 0.2 to 0.5 tonne/h and some use jaw crushers (
stone crusher
) followed by grinding with ball mills (capacity of 0.7 to 2 tonnes/h). For mineral concentration, the most popular methods are centrifuges and copper-amalgamation plates.
The centers charge between Z$ 10,000 (US$ 2.86) to Z$ 14,000 (US$ 4) per hour of grinding and concentration depends on the hardness of the ore. Using stamp mills, hard rocks take 5 hours/tonne to be ground and concentrated, whereas soft ores take 1.8 hours/tonne.
Miners prefer milling centers with stamp mills, as they believe that ball mills retain part of the gold in the internal liners. The lack of gold liberation is an evident problem when using stamp mills and this is the main reason why miners recover less than 30% of the total gold by gravity separation followed by amalgamation. Stamp mills operate with water and the pulp is discharged through a 0.6 to 0.8 mm screen into a local-made centrifuge or on copper-amalgam plates.
The concentrates from the centrifuges are given to the miners and they perform their own amalgamation. The millers provide the miners with amalgamation barrels and they do not charge extra for this service. Miners can add whatever they want into the amalgamation barrels, including soap, acids, and sodium cyanide tablets. The material discharged from amalgamation barrels is concentrated by panning in a plastic bowl and the tailings pass through an amalgamating copper plate. Some miners take home the amalgamation tailings. They re-grind, sometimes add more mercury, pan them at their backyards and roast them in kitchens. The fate of these Hgcontaminated amalgamation tailings is unknown.
It is common to see miners adding three teaspoons (150 g) of mercury in the centrifuges used for gravity concentration of gold. This “flours” part of the mercury that is lost with the tailings. The use of copper-amalgam plates is also very popular in the centers and to amalgamate the whole ore.
The great majority of miners in the region do not use retorts as they claim that the process is time consuming as they use low-temperature bonfires. Instead they put the amalgam in a tin to be burned in a wood fire without any protection. The burning process is done either under supervision of a large number of people or furtively in the bush. At low temperature, the retorting process is very incomplete. Retorted gold beads with more than 20% of residual mercury are usual.
Most of the gold is left in the primary tailings and the millers apply vat-cyanidation to extract this remaining gold. Miners receive no compensation for the extra gold extracted by cyanidation. This is a source of conflict between miners and millers. Most milling centers have 5 to 10 cyanidation tanks to extract residual gold using vat-leaching but some millers have as many as 27 tanks. About 20 to 70 tonnes of tailings from the gravity circuit and from the amalgamation process are added to cement each tank to be leached with 18 kg NaCN/tank.
