这是什么？
Six metals — platinum, palladium, rhodium, iridium, ruthenium and osmium — that occur together and are separated from each other only with difficulty.
为何重要？
They are separated as a family, so the price of any one of them is partly set by demand for the other five.

其在岩石中的来源
所有含矿矿物 →实际承载以下内容的矿物： platinum-group metals. 只有其中某种物质的富集程度足以覆盖开采成本，矿床才能成为矿体。
Sperrylite
The most common platinum mineral, a hard arsenide found in nickel-copper sulfide ores.
Pentlandite
The main nickel sulfide ore mineral, and the host that also carries most by-product platinum-group metals.
储量持有方
"储量"是一个严格的术语。它是指已知矿床中，按当前价格和当前技术，在经济上可行的可采部分——而非地下所有存量。当价格上涨或新工艺出现时，储量增加；当价格下跌时，储量减少。
