Abstract
An aqueous dust suspression and dewatering fluid comprising one or more surfactants and at least one high terpene-containing natural oil. The fluid can be used in a formulation of water dosed with the aqueous dust suspression and dewatering fluid for the abatement of dust and dewatering of particulate material. Methods are described for the abatement of dust and dewatering of particulate material using the formulation.
Claims21
An aqueous dust suppression or particulate material dewatering fluid comprising one or more surfactants in an amount of from about 15% to about 25% by weight selected from salts of fatty acids, alkyl sulphates, alkyl ether sulphonates and/or alkyl aryl sulphonates, and at least one high terpene-containing natural oil containing at least 90% terpenes selected from pine oil and/or one or more citrus peel oils, said fluid comprising amounts of said surfactant(s) and high terpene-containing natural oil(s) effective in combination for dust suppression or particulate material dewatering.
An aqueous dust suppression fluid comprising one or more surfactants in an amount, of from about 15% to about 25% by weight selected from salts of fatty acids, alkyl sulphates, alkyl ether sulphonates and alkyl aryl sulphonates, and at least one high terpene containing natural oil containing at least 90% terpenes and selected from pine oil and/or one or more citrus peel oils, said fluid comprising amounts of said surfactant(s) and high terpene-containing natural oil(s) effective in combination for dust suppression.
An aqueous composition formulated for dewatering particulate material comprising one or more surfactants in an amount, of from about 15% to about 25% by weight selected from salts of fatty acids, alkyl sulphates, alkyl ether sulphonates and alkyl aryl sulphonates, and at least one high terpene-containing natural oil containing at least 90% terpenes and selected from pine oil and/or one or more citrus peel oils, said fluid comprising amounts of said surfactant(s) and high terpene-containing natural oil(s) effective in combination for dewatering particulate material.
