Abstract: A process for separating a solid having two or more components, at least one of which is lyophobic and at least one of which is lyophilic. The process comprises, in a single step, comminuting a mixture of the solid in a first liquid to which one of the components is lyophilic and to which the other component is lyophobic and in a second liquid which is immiscible with the first liquid and which will wet the lyophobic component to form agglomerates or floes of the lyophobic component and the second liquid in a mill having positive transport capability such that the mill causes the mixture to be transported therethrough. The second liquid comprises a bio-oil, bio-diesel or combination thereof. The agglomerates are then separated from the mixture. This process may be used for beneficiating a coal containing ash.

Abstract: Embodiments of the process for isolating proteins from a defatted meal comprise extracting the defatted meal with an acidic solvent at a pH of between 2 and 6 to obtain a mixture of treated meal and a first solution of proteins. The process further comprises extracting the treated meal with an alkaline solvent at a pH of between 9 and 12.5 to obtain a mixture of meal residue and a second solution of proteins. The meal residue is separated from the second solution of proteins, and the proteins are separated from the second solution of proteins to obtain one or more protein products.

Abstract: A process for extracting seed-oil from an oil-containing seed product comprises (a) providing the seed product to a grinder; (b) providing a first liquid comprising a solvent to the grinder; (c) grinding the seed product and the first liquid to yield a slurry; (d) subjecting the slurry to a slurry extraction and slurry separation step to yield a processed seed product and a liquid product comprising seed-oil and solvent; and (e) subjecting the liquid product to an oil separation step to at least partially separate the seed-oil from the solvent.

Abstract: Sulphur control in fluidized bed combustion systems often involves adding a source of calcium to the combustor so that the calcium may combine with the sulphur. Ash resulting from such combustion often contains a significant amount of calcium which does not combine with the sulphur compounds. This invention teaches a method of reactivating that ash by grinding the ash in a positive transport grinding mill with water. The grinder causes the ash to simultaneously undergo grinding and hydration to convert the calcium to calcium hydroxide. Advantageously drying agents are added to the ground hydrated ash after grinding to facilitate the formation of acceptably crumbly pellets thereby increasing the amount of calcium available to react with the sulphur. A particularly advantageous aspect of the invention involves the use of wet coal slurries which are otherwise waste products as the source of water to be ground with the ash. The coal content of the slurry then forms additional fuel for the combustion process.

Abstract: A process is provided for the separation of a solid into its constituent lyophobic and lyophilic components by comminution and agglomeration in liquids to which the two components are respectively lyophobic and lyophilic. The process has particular application in coal beneficiation wherein ash particles are liberated into a water phase and coal particles are agglomerated with oil. The operations of comminuting and agglomerating are combined in a single step by performing the process in a mill having positive transport capability.
