Characteristics of Placer Gold. Placer gold occurs as particles ranging in size from minute grains to nuggets weighing 100 or 200 pounds. Pieces worth more than …
Traveller11, I know you called it micron gold but from your discussion it sounded like this was free visible gold (placer gold), not invisible gold in ore, If I can see the gold with my eye's I can pan it no matter how small, if it is invisible in rock, and I had an assay to prove it was there then I would consider leaching the ore.
The gold dissolution rate is dependent on the concentration of NaCN and the alkalinity of the solution, the optimum pH is around 10.5. For efficient leaching, the gold should occur as free, fine-size, clean particles in an ore.
Finally, use a gold smelting furnace to get the gold bar(If you request, we can offer it). 7. After getting all the gold concentrates, the tailings from 3 sets of sluice boxes will be sent to a spiral sand washing machine, then …
How much do you pay for gold? The following rates are to be used as a guide: 5 to 15 grams of gold -85% of spot. 15 grams to 2 ounces of gold- 90% of spot. 2 ounces of gold and above- 93% of spot. For amounts …
