Title:
MOLTEN-SALT CHLORINATED-SLAG RESOURCE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/174012
Kind Code:
A1
Abstract:
Provided is a salt chlorinated-slag resource processing method; in said method, the strong oxidizing or alkaline waste brine or chlor-alkali chemical tail-gas absorption waste liquid produced by purifying molten-salt chlorinated tail gas is used to process molten-salt chlorinated-slag leachate, thus recovering NaCl, crystallized magnesium chloride, and ferromanganese slag and performing low-cost resource processing of molten-salt chlorinated slag. The method uses waste to process waste, not only solving the problem of pollution by molten-salt chlorinated slag, but also recycling NaCl, MgCL2, and ferromanganese raw materials from molten-salt slag; it has good economic benefit and is of significant interest in eliminating the bottleneck in the development of techniques for preparing TiCl4 by titanium slag molten-salt chlorination; it is widely applicable in China and abroad among companies producing molten-salt chlorination and magnesium electrolytic titanium sponges and companies producing molten-salt chlorination titanium sponges, and has broad prospects for widespread use.
