In all experiments aimed at testing the gold content of rocks or “ore”, you should ask yourself whether the conditions of his test differ in any vital particular from those that would obtain on a commercial scale; if so, there is no guarantee that his results would be borne out in a working plant. Small scale experiments are very valuable if carefully and skilfully performed, but may be ...

2021-02-28 Nether gold ore generates in the Nether in the form of mineral veins. Nether gold ore attempts to replace netherrack 10 times per chunk in veins of size 1-10, from levels 10 to 117, in all Nether biomes. In basalt deltas, nether gold ore attempts to generate 20 times per chunk as there are fewer valid generation areas.

Most ores will have little or visible gold in them ...

Arsenic-containing pyrite in coals still poses a severe health problem for millions of people in the Guizhou province in China. Sulphur and sulphuric acid used to be produced from Pyrite ore but are currently obtained as by-products of natural gas and crude oil processing leaving very limited economic value to Pyrite so the mineral is currently mined only for specimen purposes.

Some pyrites can contain 0.25% gold by weight or more. Although this is a tiny fraction of the ore, the value of gold is so high that the pyrite might be a worthwhile mining target. If pyrite contains 0.25% gold and the gold price is $1500 per troy ounce, then one ton of pyrite will contain about 73 troy ounces of gold worth over $109,000. That is not a guaranteed money-maker.
