The Problem of Leaching – Pesticide Environmental Stewardship

Leaching is the movement of contaminants, such as water-soluble pesticides or fertilizers, carried by water downward through permeable soils. Generally speaking, most pesticides adsorb to soil particles (especially clay), become immobile, and do not leach. The fate of mobile pesticides, however, can be thought of as a race between the various degradation processes and leaching to groundwater.

(PDF) Zinc solvent extraction in the process industries

Zinc solvent extraction in the process industries. The industrial application of zinc solvent extraction for the treatment of zinc residues and furnace dust was discussed. The technique was found appropriate under operating conditions, as it eliminates the losses of valuable metals that occur with traditional precipitation methods.

It is seldom found necessary to heat the liquors in leaching proper, the strength of acid lixiviant used being sufficient to effect solution of the copper at ordinary temperatures. Most ores amenable to the leaching process carry such small quantities of the precious metals that they can be neglected.
