We undertake both smelting and assaying of gold in our facility. Smelting is done with a Hybrid combination of Gas and Electric furnace. The electric generates the fan speed and Current which assist the smelting whilst the Gas fires the process. Before smelting the gold will be washed in Nitric Acid to clean and burn off other materials to the barest minimum.
The smelting begins with the open Crucible pot, our crucibles have a weight capacity of up to 8kilos per smelting time. Smelting takes approximately 20 minutes per Crucible of 8 kilos weight. This is done in the presence of clients who if so willing to be present during the process. The material can be in any form, Dust, ingots and or Nuggets. The material is put into the crucible and boras is added to gold in the crucible to be smelted by Gas fire.
After the smelting process the gold is made into dore bars of weights between 500 grams to 2 kilo bars, after which the dore bars are sent to our Assay laboratory. The Assay process involve the usage of the specific density Hydrostatic gravity electronic scale. The gold is placed on the electronic scale in the presence of the client, the captured weight is written down and the gold placed in the vessel of water underneath the electronic scale to determine the displacement of water against the weight of the gold. The weight of the displaced water is calculated by a special formula using the Density of gold and the result is then divided by the original weight of the gold which determines the actual karat or percentage of properties in the gold bar. This method has a relative precision of 0.01 grams.
