    Abstract: The flotation reagents from acidic olive oil are made by transesterification of acidic olive oil. Acidic olive oil is olive oil having an acid value high enough to render it unsuitable for consumption, typically greater than 3.3% and/or between 3.3-7%. Transesterification of the olive oil with methanol converts fatty acids in the olive oil to an ester fraction and a glycerol fraction. The ester fraction may be sulfonated and used as the collector in a reverse flotation process, selectively removing the carbonate gangue from phosphate-carbonate rock in the froth, leaving phosphates in the sink. The glycerol fraction may be used without modification as the collector in the reverse flotation process. Both fractions are highly selective for carbonates, substantially reducing loss of phosphates in the froth.

    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 translation: 根据本公开的实施方案的絮凝剂包括核心纳米颗粒和核心纳米颗粒表面上的至少一个带正电荷的官能团。 纳米颗粒可以包括二氧化硅，氧化铝，二氧化钛，氧化铁，氮化铁，碳化铁或碳基纳米颗粒。 沥青回收方法可以使用絮凝剂来中和和聚集来自油砂矿石的沥青液滴和/或矿物颗粒。 沥青液滴聚集在絮凝剂的核心纳米颗粒周围，以形成沥青絮凝物，而矿物颗粒聚集在絮凝剂的核心纳米颗粒周围形成矿物絮凝物。 然后，浮力的沥青絮凝物可以与密集的矿物絮凝物分离，从而可以从油砂中高产率地回收沥青。
