Gold Recovery | Jacobi Carbons
Gold recovery takes place in mines across the world. Like most other industries, gold extraction must strike the delicate balance between controlling operating costs and maximising the return on investment (whilst maintaining environmental responsibility too). Choosing the right activated carbon supplier is vital to this. Almost half of all adsorption-desorption-recovery plants worldwide use ...
