The Stillwater deposits are platinum poor and palladium rich with nearly 4 times as much palladium as platinum. So although the overall grade of the ore is about 10 g per ton combined PGE's which is similar to the Bushveld the value of the ore per ton is less than half that of the Bushveld because of the relatively lower price of palladium.

Silver: Silver is generally found in serpentine, trap, sandstone, limestone, shale, or porphyry rocks, the gangue being quartz, calc, fluorite, or barite.All silver ores are heavy, and many of them are sectile, i.e., may be cut with the knife. Western men test for silver by heating the ore and dipping it into water.

Because the ore is sulfidic in nature, it was concentrated by froth flotation. A 45 kg/h process development unit (PDU) was constructed and 85 to 95% of the platinum and palladium were recovered from the ore by using mercaptobenzothiazole or sodium isobutyl xanthate as collectors.

Dec 11, 2019· Basically, what I have is an ore that is very high in metallic platinum. I have a proprietary process for extracting it and I have found that I can make it precipitate by itself as PtCl6 without the use of ammonium chloride simply by keeping the concentration very high and adjusting the PH.

Evaluation requires defining, in advance, the target indicators for outcomes and the impact of the intervention (e.g. SED project or risk / impact controls). For example: To evaluate an SED project related to capacity development, sites will need to define and measures progress against:

which will help you to decide where to drill. Copper grade is the concentration of copper in the ore rock. To calculate the grade of copper for the sample, geologists use the equation: (amount of copper metal/amount of copper ore rock)*100 2. If a deposit area has 200lbs of copper in 10,000lbs of ore rock, what is the grade? 200/10000*100=2% 3.

Silver ore can be identified in the field by evaluating the physical properties of the suspected sample or by submerging it in water.
