Assay Determination of Platinum in Ore & Gold Bullion
Mar 05, 2017 As a further test, this may be filtered off and gently ignited to produce spongy platinum. If the amount of the final metal be considerable, the platinum may be determined by the double-chloride method. Any decided difference shown would indicate the presence of other members of the platinum group, for which direct test could then be made.
How to assay and evaluate platinum, nickel and tin ores
Translucent. White. Harsh. Brittle. Cleavage, perfect. Fracture, uneven. Texture, granular crystalline. Calamine is a difficult mineral to detect without experience, as when impure it does not look in the least like a metallic ore. It would be taken for clay or shale. This ore results from the decomposition of sphalerite or sphalerite

The effect of acid is another basic test. None of the common acids will attack Pt. However, cold aqua regia (3 part HCl + 1 part HNO 3) will attack Pt, but only very slowly. Aqua regia will attack most other metals and alloys almost instantaneously. A reputable jeweller should be able to test for platinum

Minerals and Some of their Uses. Minerals have distinct & characteristic Physical & Chemical properties, & are the primary sources of all the naturally occurring Metals on earth. Minerals can be either Metallic or Non-Metallic, depending upon their compositions. A Mineral may consist of either only one Metal or a number of different Metals.

Jun 24, 2017 Recovery of platinum and palladium values decreased from more than 96 pct to approximately 70 pct. The best flotation conditions for both rougher and cleaner flotation stages were applied to 5,000-gram charges of ore. The results of a typical flotation test are given in table 10. A detailed analysis of a cleaner concentrate is given in table 11.

Apr 04, 2012 "The improved technology in the new TerraSpec line of mineral analyzers helps mineral exploration experts to more quickly map new deposits, and mining production organisations to better optimise their ore analysis, which aids in maximising metal recovery and mine longevity," said Curtiss, at the product’s launch in January 2012.
