Abstract: Methods and systems for preparing ore for precious metal extraction is provided. For example, a method comprises crushing ore; grinding the crushed ore; screening the ground ore to separate ore particles into a first group of large ore particles and a first group of small ore particles; crushing the first group of large ore particles; screening the crushed ore to separate into a second group of large ore particles and a second group of small ore particles; separating the second group of small ore particles from the screen into a third group of large particles and a third group of small particles; milling the third group of large ore particles; separating milled particles into a fourth group of large particles and a fourth group of small particles; and sending the third and fourth group of small particles for further metal extraction processing.
