Abstract: The invention provides methods and compositions for improving a froth flotation type separation. The method uses a thickener to improve the effectiveness of an emulsifier. The improvement allows for low dosages of emulsifier to work well so the emulsifier does not cancel out the effectiveness of other additives in the slurry such as collectors, frothing agents, regulators, depressors, deactivators, and/or activators.

Abstract: The invention provides a method of inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more particular silane based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.

Abstract: The invention is directed towards methods and compositions for treating piles of particulate materials to inhibit and prevent the loss of valuable fuel or mineral dust from being released from storage piles or open containers. The method involves applying to the pile a binder coating containing VAE and crude glycerin. The binder coating cures and hardens slowly so it is able to remain flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around. This coating is especially effective for coal piles and also for piles within and for being moved by open topped railroad cars. The coating's flexibility prevents the coating from becoming brittle and shattering. The coating has better performance than its ingredients do alone. The coating is effective both when it is flexible and after it cures. As a result the invention can both prevent unwanted dust pollution as well as save its users money by avoiding loss of blown away material.

Abstract: A method for increasing the floccule size and volume of alumina trihydrate during the Bayer processing of bauxite ore using a flocculant in conjunction with a water continuous polymer. The addition of the flocculant and the water continuous polymer to the alumina trihydrate slurry following the security filtration and settling producing trihydrate that is put through the calcination process to produce purified alumina or used as seed for the precipitation process.
