| Abstract: |
| Lithium is an important support for achieving the strategic goal of “carbon peaking and carbon neutralization”. Jiangxi Province is the world’s concentration of lepidolite, of which the Li2O content is as low as 0.3%. With the expansion of mining scales, the development and utilization of low-grade refractory lithium bearing ceramic clay ore urgently need to be solved. The lithium element in a low grade refractory lithium bearing ceramic clay ore from Jiangxi Province mainly occurs in ferrolepidolite and lithium-rich mica, which are closely interbedded. The ore has a high content of layered silicate minerals such as mica, which is easy to be muddled, and is not conducive to the flotation separation of lithium mica minerals. For this ore, the desliming-flotation process was |
