Modified resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These modified resins are especially useful as froth flotation depressants in the beneficiation of many types of materials (e.g., mineral and metal ores), including the beneficiation of impure coal comprising clay impurities, as well as in the separation of valuable bitumen from solid contaminants such as sand. The modified resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water. The modified resins comprise a base resin that is modified with a coupling agent, which is highly selective for binding to solid contaminants and especially siliceous materials such as sand or clay.

Modified amine-aldehyde resins and uses thereof in separation processes

A method for treating a seedling by dipping the roots of the seedling into a composition containing a slow release, particulate urea-formaldehyde polymer, which is useful as a fertilizer for enhancing the extended delivery of nitrogen needed for plant development and growth and to the composition useful as the root dip, or as a soil drench.

Slow release nitrogen root treatment

A coated aggregate material for enhancing the extended delivery of nitrogen needed for plant development and growth, the coated aggregate material having a slow release (extended-release) nitrogen coating of a particulate UF polymer adhered to the aggregate material with an adhesive binder.
