An integral structure is provided for chemical processing and manufacture, in which a plurality of laminae are joined together and having inlet and outlet ports connected by a three dimensionally tortuous channel. Chemicals are introduced through the inlet ports and processed along the channel, with desirable product withdrawn through the outlet ports. The laminae are of materials selected to be compatible with the chemical process, from the group consisting of elements of groups III, IV or V of the Periodic Table, ceramics, glasses, polymers, composites and metals. Processes of manufacture of the apparatus and processes utilizing the apparatus are also disclosed herein.

Integrated chemical processing apparatus and processes for the

A solid, water impervious landfillable composition of a process for treating iron chloride wastes such as those obtained when chlorinating titanium ore is disclosed. The process involves reacting the iron chlorides with limestone in molten CaCl.sub.2.xH.sub.2 O, where x equals 3-6. The composition comprises CaCl.sub.2.xH.sub.2 O where x is from 3-6 and FeO.sub.Y where Y is from 1.0-1.5 and the weight ratio of CaCl.sub.2.xH.sub.2 O (calculated as CaCl.sub.2.2H.sub.2 O)/FeO.sub.Y is from 1/9-4/1.
