Sintered nickel-cadmium cells have relatively thin sintered nickel matrices as the plate grid structure. These matrices are highly porous and are impregnated with the active positive or negative material in the solution state. The plates are then formed electrochemically, washed and dried. In other variations of the process the active

the storage and recycle of plant process water. However, there may be a need to treat bleed streams of some process effluents to prevent a buildup of various impurities. Solid wastes from nickel sulfide ores often contain other metals such as copper and precious metals, and con-sideration should be given to further process-ing for their recovery.

process control (Fig. 1). Fig.1: Nickel and Zinc metal price graphs7. Productivity Ideally, productivity maximization starts with the conceptual design of a new plating line, preventing bottle necks in the process flow during production. In the past, the efficiency and plating rates of alkaline zinc nickel process limited the

Finally, nickel plating can release nickel sulfate fumes. Nickel compounds are highly potent skin sensitizers and frequently cause a chronic skin condition called "nickel itch". Nickel compounds can also irritate the eyes, nose and throat. Nickel fumes have been proven to cause nasal and sinus cancers among nickel refinery workers. In ...
