Embodiment

[0042] The foregoing may be better understood by reference to the following examples, which are presented for purposes of illustration only and are not intended to limit the scope of the invention.

[0043] Tailings from mineral processing operations were used in the study to evaluate the suppression effect of dust generation under various treatment scenarios.

[0044] The treatments used include:

[0045] • Water - used in many mineral processing operations to control dust formation in holding dams and / or tailings ponds.

[0046] • Comparative Example #1: A commercially available dust control product comprising styrene-acrylate copolymer.

[0047] • Comparative Example #2: A commercially available dust control product comprising concentrated aqueous glycerin.

[0048] • Product A - Contains a 50:50 mixture of VAE copolymer and crude glycerin.

Abstract

The present invention relates to methods and compositions for treating piles of particulate material which inhibit and prevent the spread of valuable fuel or mineral dust from storage piles or open containers. The method includes applying a binder coating comprising VAE and crude glycerin to the heap. The adhesive coating slowly cures and hardens while the pile or load is still settling, jostling, bumping and moving around. The adhesive coating is capable of remaining flexible. The coating is particularly effective on coal piles, and also on piles in and / or moving through open railroad cars. The coating flexibility prevents the coating from becoming brittle and crumbling. The coatings have better properties than those shown by the components alone. The coating is effective when the coating is flexible or after it has cured; thus, the present invention can both prevent unwanted dust contamination and save the user money by avoiding blow-off material.

Description

[0001] Cross References to Related Applications [0002] Not applicable [0003] Statement Regarding Federally Funded Research or Development [0004] Not applicable technical field [0005] The present invention relates to methods and compositions for containing particulate matter in open containers including, but not limited to, open top hopper cars, trucks, buildings, similar storage devices / containers. Background technique [0006] It is known to treat large quantities of particulate material, especially coal, with binders (also known as skinning agents) to harden the surface, thereby retaining valuable material and preventing the diffusion of dust from the particles. Existing adhesives are described, among other places, in US Patent No. 5,441,566. These binders include latex, petroleum products, and pine tar resins. Other binders include: phenolic resins mixed with polyisocyanates in the presence of catalysts (described in U.S. Patent No. 5,244,473), basic phenolic ...
