Rare earth minerals (REMs) contain rare earth elements (REEs) that are important in modern technologies due to their unique magnetic, phosphorescent, and catalytic properties. However, REMs are not only non-renewable resources but also non-uniformly distributed on the Earth's crust, so the processing of REE-bearing secondary …

For example, at Mountain Pass, California, USA, and Mount Weld mine in Australia, flotation is employed to enrich rare earth oxides (REO) from 3%-15% to 40%-60% in concentrates [9,17].

Another example of industrial REM flotation is at Mountain Pass per Fig. 4.3.In this case, after comminuting the ore to a size initially below 150 microns, resulting slurries are heated to 180 °F and conditioned for approximately 10 minutes with three main reagents: soda ash as pH modifier, lignin sulfonate as depressant, and fatty acid as …

Sodium silicate is widely used as a depressant in rare earth flotation due to its ability to inhibit silicate minerals. First, the optimal dosage of sodium silicate in rougher 1 was determined using 1200 g/t of Wx in rougher 1. In rougher 2 the dosage of Wx was 600 g/t and the sodium silicate dosage was 500 g/t.
