Abstract: The instant invention relates to a process for removing tungsten, and/or molybdenum generally, as the tungstate and/or the molybdate anion, from aqueous solutions, e.g. brines by contacting such solutions with a high-surface area oxide selected from the group consisting of manganese and iron oxides, preferably manganese or iron hydrous oxide, whereby tungsten or molybdenum is adsorbed on said high-surface area oxide. The instant process provides selectivity for tungsten as well as molybdenum even though they are present in solutions containing various other materials such as sodium, potassium, calcium, etc. ions. This process is preferably applicable to removal of tungsten from high pH brines such as a brine having a pH of at least 9, for example greater than 10. The oxide adsorbent may be regenerated by contacting with an aqueous solution having a pH higher than the brine from which the tungsten and/or the molybdenum has been removed.

Additional fluorine (e.g., a fluoride compound) can be added to accellerate formation of the aluminum fluorophosphate.

Abstract: In a process for recovery of values contained in solid carbonaceous material, the solid carbonaceous material is comminuted (10) and then subjected to pyrolysis, in the presence of a solid particulate source of heat in a pyrolysis zone, to form a pyrolysis product stream (24). The pyrolysis product stream contains a gaseous mixture and particulate solids. The solids are separated from the gaseous mixture to form a substantially solids-free gaseous stream (28) which comprises volatilized hydrocarbon free radicals newly formed by pyrolysis. The solid particulate source of heat is formed by oxidizing part of the separated particulate solids (32). Condensed stabilized hydrocarbons are obtained by quenching the gaseous mixture stream with a quench fluid (76) which contains a capping agent for stabilizing and terminating newly formed volatilized hydrocarbon free radicals. The capping agent is partially depleted of hydrogen by the stabilization and termination reaction.

Abstract: Method and apparatus for recovering metal and plastic from plastic insulated wire. Plastic insulated wire is first chopped or otherwise comminuted to reduce the wire size. The bare metal, typically copper or aluminum, is separated from the insulation and insulated wire by aspiration or electrostatic separation. The plastic insulation is then separated from the insulated wire and any remaining bare metal by eddy current separation, typically in a linear induction motor, resulting in three fractions, the bare metal, the pure plastic, and the remaining plastic insulated wire pieces. The latter may be further processed, as by impact milling to separate the plastic from the metal, and then recycled to separate bare metal, plastic insulation, and insulated wire.
