  • Patent number: 12234301
    Abstract: Metal contaminants may be problematic in a number of industries, particularly in the mining industry. Fines production and dust control may be similarly problematic in many industries, including the mining industry. Reaction products formed from a saccharide polymer and diallyldimethylammonium chloride (DADMAC) under room temperature to heating conditions in the presence of a hydroxide base or a radical initiator may be effective for promoting removal of metal contaminants from clay-containing substances, such as through froth flotation. The reaction products may also be effective for mitigating fines production and providing dust control by forming a coating upon a plurality of particulates.

  • Patent number: 12194400
    Abstract: A method of processing pulp, extracted from red mud in processing bauxite, includes the following steps. The pulp is filtered to obtain a first filter cake and a first filtrate. Aluminum is leached from the first filter cake by adding, to the first filter cake, sodium hydroxide (NaOH) solution to form an aluminum-containing first slurry. The first slurry is filtered to obtain an aluminum-containing second filter cake and a second filtrate. From the second filtrate, in presence of carbon dioxide gas, first aluminum compounds are filtered out. Aluminum is leached out from the second filter cake by adding, to the second filter cake, NaOH solution to form a second slurry. The second slurry is filtered to obtain a third filter cake and an aluminum-containing third filtrate. From the third filtrate, second aluminum compounds are precipitated out which include sodium hydroaluminocarbonate and aluminum hydroxide.
