METHOD AND EQUIPMENT FOR THERMOLYTIC VACUUM PROCESSING OF SOLID PRODUCTS, WITH CONTINUOUS SEPARATION AND RECOVERY OF A LIQUID FRACTION OF THESE PRODUCTS

摘要

Method for processing solid products containing a low melting point metal, comprising heating these products in a first zone, thermolyzing (2) them in a second zone at subatmospheric pressure while collecting, by means of an externally communicating siphon (7), the liquid metal flowing from the products, after which said products are reduced in a third zone. These zones are isolated from each other and from the outside by doors forming airlocks.
