Most of the laboratories in the SGS global network offer fire assay gold determinations with an unparalleled level of analytical expertise. Lead collection fire assay is used to determine gold in all sample types, including rocks, drill core, soil and chip samples. SGS can use various sample sizes (15, 30 and 50 g), depending on anticipated
Sampling and assaying practices for gold ore reviewed with comments upon problems such as “nugget effects”, “metallics” and “hidden gold”. SAMPLING AND ASSAYING OF GOLD ORES G.W. Poling and A.J.

Our ore assay lab performs fire assays for gold and silver ores, testing daily for precious metals in trace amounts up to high grade ores and concentrates, continuously since 1954. We test all types of ores and minerals. Tests include Spectrographic Analysis for most metals and fire assays for gold and silver ores,
These CRMs represent typical feed ore samples encountered at a coppergold mine. They were first digested in an SPB sample preparation block (PerkinElmer Inc, Shelton, Connecticut USA) using aquaregia that had been made from analytical reagentgrade acids. For each sample, a total of 0.4 g was weighed into a 50 mL polypropylene

B y detecting and then measuring this signature gammaray signal, which is proportional to the amount of gold in the sample, the gold concentration and grade of ore can be easily estimated. F urthermore, the energy of the incident Xrays and emitted gammarays is high enough to penetrate several centimetres of rock easily. Therefore,
The global minerals laboratory provides sample processing facilities and a wide range of stateoftheart mineral testing services to clients wherever they are based, with mineral assay laboratories located in key mining regions and locations. Preparation of the Sample: Preparation of a Standard Mineral Sample (dry, crush, split and pulverize)
However, in some samples following acid digestion using the 3:1 ratio consisting of high levels of sulfur, beads of elemental sulfur can buildup in which gold may be secreted. Another feature that impedes the recovery of gold can be adsorption, either onto the material of the digestion vessel or onto the system that pumps the solution into the
Quality assurance and quality control. Quality assurance and quality control are the key components of a quality management system. 8–10 Quality assurance is the collation of all actions necessary to provide adequate confidence that a process (e.g. sampling, test work and assaying) will satisfy the pertinent quality requirements. While
Start with the 14K gold wire. Streak the wire across the plate beside the gold sample. Make sure the lines do not intersect. Apply aqua regia to both streaks. The aqua regia will react—bubble and fizz—if it contacts gold. The acid will turn the same color when the purity of the ore sample matches the test wire.
