leaching operations. Heap leaching provides relatively lowgrade, clear solutions from which the gold has to be recovered. In practice, carboninsolution (CIS) is generally used for the upgrading of the gold. With developments around goldselective anion exchange resins over the past few years and the recent commercialization of a number of these resins,

Understanding nitrogen in soils

Nitrogen is the nutrient most often deficient for crop production in Minnesota, and its use can result in substantial economic return for farmers. However, when N inputs to the soil system exceed crop needs, there's a possibility that excessive amounts of nitrate (NO3N) may enter either ground or surface water.

The carbon in leach (CIL) process and The carbon in column (CIC) process. During the CIP process activated carbon particles are added to the leached pulp in a counter current circuit. The counter current principle is important because the amount of gold adsorbed on the carbon is in equilibrium with the residual gold concentration in the

The carbon is first soaked in a solution of 1 to 2 % sodium hydroxide and 5 to 10 % sodium cyanide at ambient temperature. Carbons with particularly high concentrations of gold, silver, or copper may require solutions containing up to 20% sodium cyanide. The solution is then drained from the carbon until free of excess moisture. (2) Desorption

Carbon leaching increased the net losses from cropland soils by 24–105% (median: 25%). For the majority of forest sites, leaching hardly affected actual net ecosystem carbon balances because of the small solubility of CO 2 in acidic forest soil solutions and large NEE. Leaching of CH 4 proved to be insignificant compared with other fluxes of ...
