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.

Flotation of sulfide mineral species with oils

A rigid fracture brace having a rigid and non-bendable in use U-shaped member with an inner, soft-cushioned layer carried on an outer rigid layer defining an open inner cavity for laterally receiving and supporting a user's hand, adjacent to the metacarpal grouping of hand bones. The member is of high aspect ratio and is held in position by a three strap system which includes a lower thumb strap, a middle palm strap and an upper palm strap immediately below the fingers. One end of each strap is immovably fixed to the backside of the member and securement of each strap to the member includes a loop associated with each strap. Each strap further includes a two-component hook and pile fastener so as to avoid critical registration of holes and tongs. The pile component of the fastener is carried along the backside of each strap and each strap terminates with a free-end carrying the hook component of the fastener at the tip of the inside surface of each strap. The free end of each strap is adapted to be trained through associated loops of the strapping assembly. The inventive brace extends from the base of the hypothenar eminence to beyond the fifth metacarpal-phalangeal joint to support the base of the proximal phalanx of the fifth finger.

A process and apparatus for the biological production of sulfuric acid are provided. The invention utilizes a pile containing a sulfur material, an acidophilic microbe and, preferably, a packing material. The pile is aerated and contacted with an aqueous solution.

Materials and method for the biological production of sulfuric acid

A process and apparatus for the biological production of sulfuric acid are provided.

Method for the microbiological production of sulfuric acid

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.

Methods for leaching of ores

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.

Heavy liquids for use in separation processes

The subject invention provides a novel process and bioreactor for enhancing the bioleaching of metals from sulfide mineral concentrations.
