Filed:

Dec 16, 1999

Appl. No.:

09/465864

Inventors:

Tom L. Young - Tucson AZ
Kathy Bauer - Tucson AZ
Michael G. Greene - Tucson AZ
Sharon K. Young - Tucson AZ

Assignee:

Versitech, Inc. - Tucson AZ

International Classification:

B02C 2320

US Classification:

241 20, 241 21, 204162, 204163

Abstract:

The subject invention pertains to the use of non-toxic heavy liquids and slurries in the separation of components of ores, concentrates, residues, soils, and scrap. Specifically exemplified herein is the use of cesium and/or rubidium salts in separation processes. These salts are particularly advantageous because of their high specific gravity and solubility in water and, their low solution viscosities.

75739, 75741, 75743, 75744, 423 82, 423 84, 423 85, 423 86

Abstract:

Disclosed and claimed are efficient methods for leaching minerals from ores using an acidic solution such as sulfuric acid. Additional factors which can improve mineral recovery include the use of an alkali metal halide, grinding the ore, addition of a carbon source, and/or, adjustment of the temperature at which the process is carried out. Minerals such as titanium, iron, nickel, cobalt, silver and gold may be recovered by the methods of the present invention.

International Classification:

B03D 1008

US Classification:

209166, 252 61

Abstract:

This invention is directed to the use of non-sulfur containing compounds as collectors in the froth flotation of certain mineral sulfide and metallic compounds. These non-sulfur-containing compounds may be from natural sources, such as vegetable oils, or synthesized commercial sources. These non-sulfide collectors can be used singularly, in combinations, and in mixtures with known commercial sulfur containing collectors. These non-sulfur-containing collectors are compatible with common frothers.

International Classification:

B03D 1/02

US Classification:

209166

Abstract:

The invention is directed to the use of non-sulfur containing compounds and their derivatives as collectors in the froth flotation of particular mineral sulfide and metallic compounds, particularly molybdenum-containing compounds. The non-sulfur containing compounds and their derivatives may be from a natural source or synthetic. The non-sulfur containing compounds are typically compatible with common frothers. The non-sulfur containing compounds may be used singularly, with one or more derivatives, or in any combination with each other and/or known commercial sulfur containing collectors.
