    Abstract: A flocculant, according to embodiments of the present disclosure, includes a core nanoparticle and at least one positively charged functional group on a surface of the core nanoparticle. The nanoparticle may comprise a silica, alumina, titania, iron oxide, iron nitride, iron carbide, or a carbon-based nanoparticle. The flocculant may be used, in a method of bitumen recovery, to neutralize and agglomerate bitumen droplets and/or mineral particles derived from oil sands ore. The bitumen droplets agglomerate about the core nanoparticle of the flocculant to form bitumen flocs, while the mineral particles agglomerate about the core nanoparticle of the flocculant to form mineral flocs. The buoyant bitumen flocs may then separate from the dense mineral flocs to enable high-yield recovery of bitumen from oil sands.

    Abstract: A process for the flotation of non-sulfidic minerals or ores, is disclosed in which crushed crude minerals or ores are mixed with water and a collector to form a suspension, air is introduced into the suspension in the presence of a reagent system, and a floated foam containing the non-sulfidic mineral or ores is formed therein along with a flotation residue comprising the gangue polymeric esterquats as the collector polymeric esterquats. The polymeric esterquats are obtained by reacting alkanolamines with a mixture of monocarboxylic acids and dicarboxylic acids and quaternizing the resulting esters, optionally after alkoxylation.

    Abstract: The invention relates to a reverse froth flotation process for treating a calcium carbonate ore containing silicates. The process comprises the use of two collectors selected from the group consisting of fatty tri-lower-alkyl quaternary ammonium compounds, fatty di-lower-alkyl benzyl quaternary ammonium compounds, fatty lower-alkyl di-benzyl quaternary ammonium compounds, di-fatty di-lower-alkyl quats, di-fatty lower-alkyl benzyl quats, and fatty bis-imidazoline quats. The use of a combination of different quats was found to result in a synergetic performance of the collectors.
