acid method for high cocentration of gold ore
Gold Recovery
· Gold ore is different. Crush up the ore as fine as you can. Pan it to remove rock dust. Use a magnet to remove ferrites. You can use the acid bath to remove ferrites but it will take longer. Soak the remaining ore dust in muriatic acid and peroxide to remove the nonferrites.

Higher centrifugal g forces extract the free gold particles. The InLine Spinner is perfect for low water consumption operations and will produce a smelterready product. If the ore product contains a combination of coarse and fine free gold, the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higheryield product.

Acid Mine Drainage
Of note for future mine development, 90% of the mines that predicted "low" acid mine drainage potential had acid mine drainage problems at the time of the study. In Alaska. Acid mine drainage is a problem at a number of active Alaskan metal mines including Red Dog, Greens Creek, and Kensington Mine.

Humic acid from leonardite do not influence soil pH and increase the solubility of Cu, Zn, Ni, Cr, Cd, Pb, As and Ba from soils. Fulvic acid decreased soil pH and metal solubility, except for As at the lower dose ( µL g1). The initial soil heavy metal concentration affects the processes involving humic substances.

Acid baking with sulfuric acid is a very common process. The powdered ore is mixed with concentrated sulfuric acid and baked at temperatures between 200 and 400 °C for several hours. The resulting cake is leached with water to dissolve REE as sulfates. Optimal reaction conditions and reagent use have to be matched specifically with each tested .
