Patent CA-2518509-C (CA)
Inventor: ALTMAN GREGORY H
IPC: A61F/
Filed: 2004-03-11
Granted: 2014-04-29
Abstract: Silk is purified to eliminate immunogenic components (particularly sericin) and is used to form tissue-supporting prosthetic devices for implantation. The fabrics can carry functional groups, drugs, and other biological reagents.  Applications include hernia repair, tissue wall reconstruction, and organ support, such as bladder slings. The silk fibers are arranged in parallel and, optionally, intertwined (e.g., twisted) to form a construct; sericin may be extracted at any point during the formation of the fabric, leaving a construct of silk fibroin fibers having excellent tensile strength and other mechanical properties.

Title: Precious metal recovery using thiocyanate lixiviant
Inventor: WAN RONG YU
IPC: C22B15/00
Filed: 2004-03-25
Granted: 2010-05-25
Abstract: Precious metal-containing mineral material is subjected to an acidic thiocyanate leach to dissolve the precious metal as a precious metal-thiocyanate complex. A feed of the thiocyanate leach solution may include a large molar ratio of ferric iron to thiocyanate. Precious metal may be removed from pregnant thiocyanate leach solution, such as by transferring precious metal from precious metal-thiocyanate complex to precious metal-cyanide complex and then loading the precious metal-cyanide complex onto an adsorbent material. Remaining cyanide in the thiocyanate leach solution may be converted to thiocyanate for additional leaching of precious metal.
