The present invention generally concerns a concentrated sugar additive comprising (a) raffinate derived from citric acid recovery industry and (b) sugar-containing solution useful for controlling dust emission from particulate materials during manufacturing, handling, storage or transportation. Such particulate materials comprise fertilizers, minerals, coal, etc.

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 separately to the pile two different compositions. When separate the two compositions are low viscosity and easy to spray. When combined the two form a gel coating that is resistant to erosion but is flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around. This coating is especially effective for coal piles, iron ore piles, and also for piles within and/or 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. 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.

This disclosure describes formulations and methods for dust control, for example, coal topping, a term which refers to the application of liquid products to the top of coal loads, such as those in open topped coal hopper railcars as commonly used today to transport coal. Disclosed herein are wax-based emulsion formulations that accomplish dust control during industrial operations in which dust handling is required.

Dust poses a significant threat to human and environmental health. In 2015, an estimated 4.2 million deaths, as well as numerous health issues, were attributed to dust. Unlike other major contaminant transport pathways (e.g., water, soil, biota), atmospheric transmission is relatively unobstructed, able to rapidly transport large masses of materials over long distances and broadly impact areas downwind on local to global scales. Accordingly, dust affects global biogeochemical cycles, pollutes water bodies and air masses, and impacts global climate. Therefore, developing innovative, environmentally-compatible technologies capable of mitigating dust emissions is crucial to protect human and environmental health from mining related dust. The present invention features a method for suppressing dust from a substrate surface, said method comprising applying an effective amount of dust suppressant composition to said substrate surface, wherein said dust suppressant composition comprises an aqueous solution of a glycolipid.

Methods of and systems for dispensing dust suppressant are provided. The methods comprise forming an aqueous dispersion stream by delivering a surfactant composition to an aqueous liquid stream. The aqueous dispersion stream is mixed to form a dust suppressant. The dust suppressant is dispensed to a surface at a pressure sufficient to provide coverage of the surface. Surface tension of the dust suppressant is measured via a tensiometer, and the measurement is relayed to a controller. The forming of the aqueous dispersion stream is adjusted according to the measured surface tension relayed to the controller. The systems are configured to carry out one or more of the provided methods.
