Gold Mineral Properties
Native gold is an element and a mineral. It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties - some of which are unique to gold. No other element has more uses than gold. All of these factors help support a price of gold that is higher than all but a few other metals.

Gold leaching from ores using biogenic lixiviants – A review
Biogenic lixiviants have the same restrictions as chemically generated cyanide when it comes to extracting gold from refractory (i.e., sulfidic) gold ores. As a result, refractory gold ores require pretreatment (such as biooxidation, pressure oxidation, or roasting) before being given to the bacteria for the extraction of gold. Furthermore, no ...

How dependent was Nazi Germany on iron ore from Sweden?
I think I read somewhere that Swedish Iron was 98% pure, while other ores were typically only 33 to 50% pure (but cannot find the source now). However, I think any ore can be refined to pure Iron. It just takes more work to refine 33% ore than 98% ore. Germany should be capable of using low-quality ore, but just takes more work. –
