What does barite mean? A yellow, white, ... Barite occurs as flattened blades or in a circular pattern of crystals that looks like a flower and, when colored red by iron stains, is called a desert rose. ... The mineral is regularly found associated with massive barite or calcite.
Fluorite, barite and calcite are important industry minerals. However, they often coexist, presenting difficulty in selectively separating them due to their similar surface properties. In this study, valonea extract and sodium fluosilie were used as depressants to selectively separate them by flotation, with sodium oleate as the collector.
The calcite encrusts most of the matrix, with clusters of blue bladed barite stered across the calcite. This is a truly aesthetic specimen that would make an excellent addition to any mineral collection.

The calcite crystals are complex and unusual – they are little towers of composite parallelgrowth scalenohedral crystals, with naturally hollowedout terminations.
· 1. Introduction. Barite with a formula of BaSO 4, is deemed to be an important raw materials of nonmetal mineral which has been used in a wide range of padding, gas drilling mud, barium chemical industry and weighting agent of oil, etc.[1,2].It is mainly existed in the low temperature hydrothermal veins rock. Generally, quartz, fluorite and calcite are the commonly minerals that .
There is a patch of tabular barite blades near the middle of the specimen (which look like teeth), and that's how we know it is from Illinois. Tennessee baryte combos are botryoidal. Anyway, this is an excellent specimen which is from the Ex. Ray Berry Collection (#1791).
