Title: Recovering method for gold from slime after copper electrolysis
Inventor: IIO TOSHIMASA
IPC: C22B11/06
Filed: 1980-11-18
Abstract: PURPOSE: To early recover gold from slime after copper electrolysis in a high yield by removing copper and selenium from the slime and treating the slime with gaseous chlorine.  
     CONSTITUTION: Slime after copper electrolysis is freed of copper and selenium by various methods. This slime is coverted onto an aqueous slurry, and by blowing gaseous chlorine into the slurry, they are reacted with stirring. Thus, gold in the slime is leached out. This leaching reaction is considered to be the end when bubbles of unreacted gaseous chlorine begin to form, or the reduction of the amount of gaseous chlorine is stopped. Since elemental gold particles in the slime are fine and have high reactivity with chlorine, gold can be leached efficiently. After separating and removing the residue, the soln. contg. the  leached gold is treated with a reducing agent to directly obtain high grade gold. The gold-free soln. can be supplied to the next process such as a process for recovering a platinum group metal. On the other hand, the gold extraction residue is supplied to a process for recovering silver.

Patent JP-S6059676-A (JP)
Title: Compliant press engaging electric contact and method of producing same
Inventor: UEIN II MANSUKA
IPC: H01R12/58
Filed: 1984-08-02
Abstract: A compliant, press fit, electrical contact includes a relief groove which forms an area of reduced cross sectional thickness to provide a stress concentration, and thus a controlled region of plastic flow, to create a plastic-elastic hinge. When the contact is inserted into a plated through hole in a printed circuit board, the hinge elastically deforms until a predetermined push-in force is reached, at which time a controlled plastic flow begins. Once the point of plastic flow is reached, the amount of additional push in force required for additional deflection of the hinge is greatly reduced, so that smaller hole sizes may be accommodated with a relatively small additional push in force. However, the required minimum pull out force is maintained for the entire range of hole sizes, since elastic energy remains stored in the hinge, even after plastic flow begins. The contact is manufactured through a series of simple coining and punching operations, so that complex rounding and rolling operations are avoided.
