A process for recovering a first mineral comprising the steps of: (a) providing a pulp comprising solids and water, wherein the solids comprise the first mineral; (b) adding a first depressant to the pulp; (c) subjecting the pulp to a froth flotation process to produce a froth comprising the first mineral; and (d) recovering the froth; characterized in that the first mineral is a sulfide mineral, and the first depressant consists of one or more dithiocarbamic acids or salts thereof of formula (I). A composition comprising the first depressant, and further comprising one, two or three of a collector, a second depressant and a mineral. The use of a dithiocarbamic acid or salt thereof of formula (I). The dithiocarbamic acid or salt thereof of formula (I) which is 3-ammo-1,2-propanediol dithiocarbamic acid or a salt thereof, 2-amino-2-methyl-1,3,-propanediol dithiocarbamic acid or a salt thereof, or N-phenylethylenediamine dithiocarbamic acid or a salt thereof.

A method for enriching lithium from a lithium clay includes the following steps (1) the raw ore were crushed to produce fine particles, (2) performing rougher on the fine particles by adding ferric sulfate or ferric nitrate, sodium oleate, and cocoamine to obtain rough concentrate and rough tailing, (3) finely separating the rough concentrate to obtain the first part of concentrate, (4) re-grinding the rough tailing by ball mill, (5) performing rougher on the reground tailing to obtain reground rough concentrate and re-ground rough tailing, (6) performing cleaner on the reground rough concentrate to obtain the second part of concentrate, and (7) performing scavenger on the reground rough tailing to obtain the cleaned tailing.

The present invention discloses mining collector compositions containing sodium metabisulfite and a thiocarbonate compound. Flotation processes for recovering molybdenum from a copper-molybdenum concentrate using the collector compositions also are disclosed.

Described herein is a method for the recovery of two major valuable lithium minerals (amblygonite and spodumene), a cesium mineral (pollucite) and quartz. The method comprises a series of direct flotation processes combined with reverse flotation processes that were designed to recover these lithium and cesium concentrates.
