A continuous contacting device is disclosed wherein a fluid stream may be contacted with particulate exchange materials. The device includes a plurality of rotating chambers filled with particulate material. Fluid is supplied individually to these chambers through a plurality feed ports which are in periodic fluid communicating relation with each of the chambers. A plurality of fixed discharge ports which are likewise in periodic fluid communicating relation with each of the chambers is also provided. A process for continuously contacting fluids with the solid particulates is also disclosed.

The method of the present invention is a novel comprehensive process for maximizing the recovery of valuable mineral values from coal ash. Options may also be included for the production of saleable inorganic chemical by-products. The process employs both physical and chemical extraction techniques that maximize the yield of products while reducing the quantity of waste produced. Valuable minerals and chemicals such as cenospheres (hollow microspheres), carbon, magnetite (Fe.sub.3 O.sub.4), alumina (Al.sub.2 O.sub.3), iron oxide (Fe.sub.2 O.sub.3) and iron chloride (FeCl.sub.3) may be produced. Due to removal of carbon, magnetite, and iron oxide from the coal ash, the processed ash comprises a quality pozzolan.

A separation device designed to effect substantially continuous separation and/or fractionation operations as in, for example, ion exchange or other solid-fluid contacting systems. Also disclosed and claimed is a method for effecting such continuous treatment of plural fluid streams. The device is characterized by its construction to permit treatment of plural streams simultaneously and continuously. Fixed inlet and outlet nipples are provided for introducing and removing the fluid streams, and the inlet and outlet nipples are operatively interconnected by a rotating member which is internally divided into a plurality of working sections. By virtue of the rotatable construction of that member and its plural working sections, discrete fluid streams may be treated separately, yet simultaneously. Furthermore, the device of this invention is such that fluid flow in either of two directions may take place through each of the working sections dependent only upon predetermined process parameters.
