Granted: 2010-01-12
Abstract: Processes are provided for recovering precious metals from refractory materials using thiosulfate lixiviants and an oxygen-containing gas at or above atmospheric pressure. The processes can employ lixiviants that include at mo st only small amounts of copper and/or ammonia to control the degradation of the thiosulfate lixiviant. The process can also operate at a relatively low pH, in relativel y inert atmospheres to control the production of polythionates which can complicate the recovery of the precious metals. The processes of the present invention provide relatively high rates of precious metal recovery.

Title: Water feed controller for a boiler
Inventor: MERWIN JEFFREY C
IPC: F22D5/26
Filed: 2005-12-09
Granted: 2010-03-23
Abstract: A water feed controller which can provide for the addition of a preset fixed amount of water to be added after a low water condition is removed. This system provides for a preset fixed amount of water to be added to a boiler above the amount which triggers the low water condition. This generally inhibits excess cycling from the boiler operating at its minimum safe water level as well as inhibiting overfilling of the boiler. Further, there is discussed a water feed controller which can measure the amount of water added over a prior predetermined period (such as 30 days) which serves as a floating window of time so that a leak or other condition resulting in overly frequent filling can be detected quickly.
