There are also method to electrolyse aluminum chloride (no CO2 exhaust but Cl, maybe recycleable to clay extraction) Diffrent Alumina extraction processes Acid process from clay. Alumina (alumium ore) extraction from clay. Bauxite are rare minera, clay are common so chemical process based on clay- not bauxite.

The research on Li extraction from Li-bearing clay minerals must focus on methods with higher efficiency and lower energy consumption, compared to the industrialized H 2 SO 4 method (Swain, 2017). To achieve this, the roasting of clays with carbonates and sulfate must be carried out at lower temperatures to avoid energy-intensive phase transfer.

This study focuses on characterizing the thermoluminescence (TL) and optically stimulated luminescence (OSL) of quartz in burnt clay, pottery, and the sediments unearthed from a Neolithic site, the Beicun site of the Liangzhu culture. It shows that the initial OSL signals (within 0.8 s) of most burnt clay and pottery sherds are not dominated by the fast component.

Ball clay is extracted predominantly from opencast workings. However, a small quantity of high quality clay is still extracted from underground mines in cases where surface access is impracticable and where higher production costs can be justified through exploitation of quality reserves. Nevertheless, as a result of economic considerations ...

The geology, types of ball clay, occurrence and extraction methods are different in each of the 3 deposit, but they are all composed of the clay mineral 'kaolinite'. The name 'ball clay' comes from the early working methods, when the clay was cut into cubes using thirting spades, tubils (lumpers in North Devon) and poges.
