Streak Test. You can use your fingernail to make an indent to see if there's a yellow streak. Gold is soft and easily scratched with a fingernail, but other minerals are more rigid and hard. Using a streak plate, scrape your specimen over the plate, applying firm pressure. The streak should be a yellowish-gray color.

Pressure oxidation is a widely accepted method to treat refractory gold ores. Gold recovery is generally lower from alkaline than acidic pressure oxidation discharge due to passivation and incomplete oxidation of mineral. Gold ore from Goldstrike, NV, is a typical refractory gold ore containing sulfide and carbonaceous matter. Alkaline …

Refractory Ore Pretreatment Processes. A "fine" grind in a gold production plant might produce a particle size distribution in which 80% of the ore is finer than 44 µm. Ultra-fine grinding can be defined as a process that produces an 80% passing size of 20 µm or less. Depending on the size distribution of gold particles, ultra-fine ...

Scratch test Gold is a very soft element, so scratching it will leave marks. Use a knife to try and scratch the surface of your rock. If it's gold, you'll see scratches. Pyrite will be too hard to be affected, and mica will flake off when scratched. If you don't have a knife handy, scratch gold with a piece of copper (like a penny).

Carbon–arsenic-bearing gold ore is a typical complex refractory gold resource. Traditionally, xanthate was often used as a flotation agent to separate gold minerals. But, in this paper, in order to reduce the cost of the agent, kerosene was used as an auxiliary collector, and the gold grade and recovery rate were increased by about 10 …

The models provide insight into the transport of fluids through low-permeability rocks with isolated, but more permeable faults. Mineral precipitation patterns resulting from chemical reactions during the coupled processes are also computed. The results are relevant to understanding the relationship of gold ore deposits to faults.
