7/296486

Inventors:

Brian Ball - Salt Lake City UT

Assignee:

Newmont Gold Co. - Carlin NV

International Classification:

C22B 1104

US Classification:

75118R

Abstract:

The recovery of precious metals from refractory carbonaceous and sulfidic ores or concentrates is improved by subjecting an oxidized slurry of this type of ore to thiourea leaching in the presence of carbon instead of subjecting the slurry to cyanidation leaching.

International Classification:

B03D 114

US Classification:

209167

Abstract:

A scheelite concentrate is recovered from a scheelite ore containing silicate minerals and other calcareous minerals by froth flotation which process comprises grinding the ore sufficiently fine to liberate the scheelite grains, pulping the gound ore with water to form a slurry containing between about 20% and about 40% solids by weight, sequentially conditioning the slurry with at least one alkali metal carbonate in small but effective amounts to provide an alkaline pH adjustment and a source of carbonate ions, with small but effective amount of alkali metal silicates to depress siliceous and calcareous gangue minerals other than scheelite and with a fatty acid collector in small but effective amounts to coat the scheelite grains, the conditioning with the fatty acid collector being conducted with sufficient agitation to disintegrate floccules of scheelite, silicate mineral and other calcareous mineral grains and to preferentially reflocculate the scheelite grains for a period of time sufficient to produce upon flotation a concentrate having a grade of at least about 50% WO. sub. 3, adding a frother to the collector conditioned slurry and subjecting the collector conditioned slurry to froth flotation to recover the froth product a scheelite concentration having a grade of at least about 50% WO. sub. 3.

Abstract:

Interactive electronic push notifications are utilized to remotely facilitate collateralized arrangements. An identifier of an article that is being offered as collateral is received from a first computer system. A unique identifier and a score associated with a first user is accessed. The article identifier is matched against a second database to identify a second computer system that has subscribed to notifications associated with the article identifier. An electronic notification is generated for the second computer system that includes the article identifier, the unique identifier, and the score. An offer for an amount of a collateralized against the article associated with the article identifier is received from the second computer system. The offer received from the second computer system is sent to the first computer system. A response is received from the first computer system associated with the offer from the second computer system.
