FIRE ASSAY WITH ATOMIC ABSORPTION

In order to increase the sensitivity and accuracy of fire assay when determining gold grades less than 2-4 g/t, a combined method is used: fire assay melting followed by spectral determination of gold and silver. The gold-silver bead obtained as a result of fire assay melting is dissolved in aqua regia, after which the solution is analyzed.

The most common methods to complete fire assay of precious metals are atomic absorption spectroscopy (AAS) and inductively coupled plasma atomic emission spectroscopy (ICP AES). Modern devices allow to determine the smallest amounts of a substance in solutions. In particular, the fire assay- AAS method may be used to determine Au grade from 0.05 g/t.
Fire assay completed with spectrometry is widely used in modern laboratories.

Tests

Bottle agitation

These are process ests of the ability of ores to be leached by dynamic cyanidation. The tests provide primary information on the recoverability of precious metals and the consumption of reagents.

Column test

Ore leaching tests using the percolation method. This method allows to create conditions that are as appropriate as possible to the industrial process.

Various process tests

To solve process tasks our laboratory carries out different types of tests according to regulations and conditions provided by the Customer.

There are many types of process tests, depending on the types of ores or products of their processing. In our laboratory, gravity concentration tests are carried out using the Knelson KC-MD 7.5 concentrator and the SKO-1 laboratory concentration table. Bottle agitation and laboratory column leaching tests (column tests) are common for ore raw materials.
