  • Cyanide Leaching Of Gold mine-engineer

    The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% -0.05% NaCN. The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve.

    What is cyanide and why do we need cyanide-free gold leaching process? Cyanide (CN–) has been used since 1889 to recover gold from hard rock. As sodium cyanide (NaCN), it reacts with gold, oxygen (O), and water (H2O) to form a gold cyanide complex (Na

  • PROCEDURE FOR DETERMINING ROCK WEIGHTS, SIZES

    After the weight and “d” of each rock (except small rock, gravel) are determined, they need to be accumulated into sizes that would be held on a particular screen size such as 1.5 D50, D50, etc. The weights of the rocks that have a “d” greater than the screen size are accumulated and considered retained on the screen.
