The present invention provides improved methods for purifying and/or removing multiply charged cations and suspended solids from water. In particular the process relates to an additive composition that has the appropriate surfactant characteristics for effectively removing multiply charged cations and suspended solids from an aqueous or oil/aqueous mixed phase via foam fractionation. According to the invention, a hydrophobically modified polymer that acts as an associative thickener is used in the presence of a source of alkalinity or anionic reactant as well as surfactant in appropriate ratios to facilitate multiply charged cation and suspended solids removal for water purification in any of a number of commercial, environmental and industrial applications.

Provided is a method of beneficiating an ore including contacting an ore with a compound represented by formula (1): ##STR00001##
where the structural variables are defined herein.

The present invention concerns a process for manufacturing white pigment containing products. The white pigment containing products are obtained from at least one white pigment and impurities containing material via froth flotation.

A process for treating and dewatering tailings comprising fine clay minerals, fine rock-forming minerals and water is provided, comprising treating the tailings with a sufficient amount of a collector to modify the surface properties of both the fine clays and rock-forming minerals; subjecting the treated tailings to froth flotation to form a fine clays and rock-forming minerals froth layer; and recovering the froth layer and subjecting it to dewatering.

A family of amine mining collectors that uses alkoxylates allows for the easy adjustment of solubility and molecular weight useful because anionic and cationic mineral collectors require such varying degrees of solubility and molecular weight. The family of the present invention allows for the optimization of both parameters and an increase in collector efficiency.

In various exemplary embodiments, a system and an associated method to retrieve information related to marketplace items within an electronic environment are disclosed. A network architecture comprises a listing module to store the information related to the marketplace items. The related information includes one or more user-created items such as an image of a model with one or more tagged items worn by the model. Each of the one or more tagged items has associated descriptive metadata. A communications module is arranged to receive a query including search terms related to social fashion items from an end-user. A query engine is coupled to the communications module to match the search terms contained within the query to the associated descriptive metadata of the tagged items in the listing module. A processing module then displays to the end-user the model and the one or more tagged items.

The present invention provides improved methods for purifying and/or removing oily particles, and/or contaminants suspended or dissolved in water. In particular the process relates to an additive composition that has the appropriate surfactant characteristics for effectively removing an oil phase from an oil/aqueous mixed phase via foam fractionation. According to the invention, a hydrophobically modified polymer that acts as an associative thickener is combined with surfactant in appropriate ratios to facilitate oil removal for water purification in any of a number of commercial, environmental and industrial applications.
