摘要： The present disclosure relates to a zinc-based alloy coating for steel strip through a continuous galvanizing process. This zinc-based alloy coating provides the steel with cathodic protection before and after the steel is press hardened processing at a high austenitization temperature up to 950°C. The zinc-based alloy coating also reduces or eliminates the susceptibility to liquid metal embrittlement during or after welding for various types of non-press hardenable advanced ultra high-strength steels. The zinc-based alloy comprises at least one element selected from manganese (Mn) and/or antimony (Sb).

摘要： A process for recovering copper from heap leach residues containing residual copper, includes identifying a production zone within the heap leach residues for secondary leaching, drilling wells into the heap at locations suitable for delivering leach solution into the production zone, injecting the leach solution including ferric ions through the wells and aerating the production zone to facilitate oxidative reactions within the production zone, and collecting effluent from the heap for copper recovery therefrom.

摘要： A method and apparatus for continuously casting lead alloy strip on a casting surface on substantially the upper half of a rotatable casting drum from a pool of molten lead alloy at a high speed comprising imparting a coarse texture to the casting surface, providing a tundish containing a pool of the molten lead alloy at a predetermined temperature adjacent a substantially vertical upwardly-moving portion of said casting drum, the tundish having a graphite lip insert having an open front defined by a Hp insert floor and opposed sidewalls cooperating with and commencing at a substantially vertical portion of the casting surface to contain said molten lead alloy in the lip insert, controlling the height of the surface level and temperature of the molten lead alloy in the lip insert, moving the casting surface upwardly through the pool of molten lead alloy by rotating said drum for depositing the lead alloy thereon, cooling the casting surface of the drum to solidify a strip of the lead alloy on substantially the upper half of the rotatable casting drum, and stripping the strip from the casting surface. The molten lead alloy preferably is a antimony-lead alloy containing about 0.3 to 5.0 wt% antimony, the balance essentially lead.
