Of all the methods of extracting gold processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...

of gold): A certain amount of iron sulfate (per one gram of gold: g of iron sulfate) was dissolved in warm water and gradually added to the goldcontaining solution. For better dissolution of iron sulfate, some drops of HCl can be used. Step 6 (washing and purifying gold deposits): The deposit was coated with HCl and then boiled (to dissolve

This pushes the gold foils off the filter and into the cup. Then, wait for the gold foils to settle to the bottom and get as much water out. After that, you could wait for the water to evaporate out and you are left with just gold. However, the gold foils tend to stick to the cup, so I keep mine in a glass vial with some water.
