ANALYSIS OF SULFUR AND CARBON BY INFRARED ABSORPTION

The content of total carbon and sulfur is determined by oxidative melting (in the oxygen current) on a LECO gas analyzer, model SC-144DR.

The analyzer is designed for rapid analysis of the total carbon and sulfur content in ferrous, non-ferrous metals, steels and alloys, ore raw materials, concentration products and other inorganic materials. They are used in the metallurgical, machine-building industry and other fields of science and technology. The principle of operation of the analyzer is based on the burning of subsamples placed in special ceramic crucibles in an induction furnace and the subsequent measurement of the carbon and sulfur content in gaseous CO2 and SO2 by infrared absorption. Measurements are carried out in accordance with the measurement procedures. The operation of the device is controlled by a computer, in the memory of which up to 32,000 assay results are constantly stored.
Measurement range of mass fraction, %:
carbon 0.0004-100 %
sulfur 0.0004-26 %

Accuracy, %:
carbon, sulfur-0.0002
The nominal analysis time is 40 seconds.

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.
