Evaluation of a novel depressant PMAA for the …
The high purity calcite was obtained from Lianyungang, China, and the fluorite fetched from Sijiazhuang, China. Both of the minerals were crushed respectively by hammer, and then the crushed samples were dry ground by ceramic ball mill. After that, the size distribution of +37-74 µm was obtained by sieve for micro-flotation.
Calcite
Calcite is a calcium carbonate mineral, which is the most common of natural calcium carbonate. Therefore, calcite is a widely distributed mineral. The crystal shapes of calcite are various, and their aggregates can be clusters of crystals, and can also be granular, massive, fibrous, stalactite, earthy, etc.
