Mining Industry

The following products manufactured for the mining industry are used in the analysis of precious metals:

• Assay Litharge – Assay Litharge is a unique type of lead oxide used in the analysis precious metals. It is produced from highly refined lead and offers a very low level of precious metal impurities. It is greenish yellow in colour, the green being due to the free lead which is characteristic of its method of manufacture.

• Gold Free Litharge – Gold free Litharge is a special type of lead oxide used in the analysis of gold and other precious metals. It is produced from specially refined lead and offers a very low level of gold. It is greenish yellow in colour.

We also have granular assay and Gold Free Litharge available where a non-dusting form is required.
