low grade gold ore MetallurgistMineral

2020-6-2  Hello i am from Indonesia, We currently had a bulk of about 500,000m/t oxide ore grade from 0.4-0.7grams per ton, there is no visible gold. At first we plan to do dump leaching but the test show only 35 percent recovery and after crushing to minus 1 inches recovery shows 75% after 6 weeks and we also did a vat leaching test it show 88% recovery after 3 days at the size of minus 1 mm.
