Fire Assay Procedure - Mineral Processing & Metallurgy
The elements osmium, ruthenium and iridium are lost during the standard lead assay and cupellation process. Instead, they have been determined using the nickel sulphide collection technique. The nickel sulphide technique uses a 10 g of sample, 1 g powdered Ni, .8 g S, 12g soda ash, and 24 g borax. The mixture is fused at 1010 °C for 1 hr.
US7364717B2 - Process for converting nickel to nickel ...
A preferred embodiment of the present invention provides a process for making nickel sulfate by converting nickel metal into nickel sulfate, which may be converted to nickel hydroxide. Nickel metal is dissolved in sulfuric acid and oxygen containing gas is introduced to produce a nickel sulfate solution having nickel sulfate and water as illustrated in the following chemical equation.
Sampling for Assaying - Mineral Processing & Metallurgy
Sampling for Assaying. Sampling is the most important procedure in arriving at the value of an ore. Improper sampling makes other procedures, including assaying, valueless, as the sample must truly represent the ore from which it is taken. Before sampling, clean fresh faces must be exposed in order to prevent the possibility of salting.
