发明名称 Method for the segmented mining and drying of bentonite
摘要 A method for drying, curing and mining bentonite clay in a clay pit wherein that overburden of non-clay material which may exist is removed and the surface of the bentonite ore body is tilled to loosen or break up a tier of the bentonite to expose it to the natural drying and curing effects of the atmosphere, the dried and cured tier of bentonite is removed thus exposing another tier of uncured bentonite, which is again tilled for drying and curing, and the process is repeated until the bentonite ore body is exhausted.
