Micro-flotation experiments confirm that the flotability of bastnaesite is high at pH 6.5−8.5, while calcite floats at pH 8.0−9.5, and barite has little flotation response. The results of FT-IR, XPS, and zeta-potential measurements indicate that there is chemical adsorption of SHA on the bastnaesite surface, and physical adsorption also occurs.
Barite Flotation Separation Process. If barite ore contains a high barium sulfate (BaSO4) content, it is associated with gangue minerals such as quartz, calcite and fluorite. Flotation machine is often required to separate the valuable barite from other minerals present in the ore. The flotation process involves adding reagents to create …

1. Introduction. As a non-metallic mineral, fluorite is commonly appeared in industrial processes related to fluorine. It is often found with the emergence of other calcium and silicate minerals such as quartz, barite, and small amounts of pyrite [1,2].The flotation for the separation and purification of fluorite from these associated minerals is based on …
Barite is a critical mineral that finds applications in many industries. The mineral is commonly occurred in deposits formed in a variety of geological environments where other semi-soluble minerals such as calcite and fluorite are also present. Because of decreasing ore grade, the mineral processing of barite nowadays becomes increasingly …

In barite flotation, sodium oleate is widely used as a collector in a highly alkaline pulp, but it is susceptible to slime and hard water ions (Gurpinar et al., 2004;Chen et al., ...
Abstract This research aimed at recovering metals retained in the tailings from the flotation of copper (Cu) and cobalt (Co) ores conducted at the New Concentrator in Kipushi (NCK). Metals retention in the tailings (0.73% Cu and 0.37% Co) increased due to the removal of the gravity separation section from the processing circuit together with …

The flotation of bastnaesite, as a major mineral source of rare earth elements, attracting much attention in the mineral processing field, is challenging owing to the natural flotability of calcium-bearing minerals. To promote the application of flotation, we systematically investigated the flotation behavior of bastnaesite, barite, and calcite, …
