Abstract: The invention relates to a method for producing an agglomerated product containing alumina which is useful as a component to be incorporated into a synthetic slag as used in steel making. The product is formed from powdered aluminium dross which is formed with water into pellets or briquettes and wherein the components of the pellets or briquettes are allowed to react at elevated pressure to release ammonia. The pellets or briquettes may then be calcined.

Abstract: Aqueous concentrates containing glyphosate herbicide which on dilution give spray solutions having higher herbicidal unit activity than prior art solutions comprise:(a) solubilized glyphosate equivalent to at least 40 grams per liter of glyphosate acid;(b) a surfactant which is (i) an amine having the formula ##STR1## where R represents a straight- or branched-chain alkyl or alkenyl group having from about 8 to about 22 carbon atoms, A represents an alkylene group, for example an ethylene or propylene group, and n and n' are integers such that n+n' has a value of from about 2 to about 8, (ii) a mixture of such amines having different groups R, the average number of carbon atoms in the groups R being from about 8 to about 22, or (iii) a mixture of such amines having different values of n and n', n and n' being integers such that in the mixture the average value of n+n' is from about 2 to about 8, R having a single value or an average value as in a mixture (ii);and optionally (c) an agriculturally acceptable in
