The ISO 8868:1989 standard offers instructions for fluorspar sampling and sample preparation. The standard describes sampling techniques from a variety of sources, including conveyors, wagons, containers, ships, stockpiles, and bagged material, during loading or discharge. It is applicable to all grades of fluorspar.
Sampling equipment is designed to avoid contamination or loss of final composite samples by minimising sample preparation errors, and avoiding sample bias. In addition to the above-listed range, Multotec's Cross Stream Sampler is used in collecting accurate and repeatable samples of your wet or dry mineral streams.

The flotation tailing is then pumped to a thickener for reagent removal and pulp densification prior to fluorspar conditioning and flotation. Flotation of Fluorspar. The thickened tailing from the barite section is subjected to two-stage conditioning in order to effect depression of the gangue in the first conditioner using depressant 60.
Finally, a flotation step was performed to depress silicate minerals in the tailings fraction and thus to improve fluorspar grade in the concentrate.
