Both battery design and environmental pressures are forcing the secondary lead industry to consider new and different processes. Trends in battery design are making normal decasing increasingly difficult. Lead in air, sulfur dioxides, and solid/liquid waste heavy metal restrictions are tightening. There is no clearly defined industry trend toward a given process, but it is clear that plants will be larger, less labor-intensive, and automated.

A unique freeze conditioning agent (FCA) which functions by forming structurally weak ice rather than suppressing the freezing point of water has been successful in alleviating frozen coal problems. Frozen coal treated with FCA has been quickly unloaded at temperatures below -17.8°C (O°F). Other applications of FCA include deicing: conveyor belts, idler, idler arms, and other moving parts that have been impeded by ice.

Beall: Mr. Donovan, would you tell me something about your early life, leading up to your going into I he mining industry? Donovan: I was born in St. Charles, Minn., on November 18, 1879. At that time my father was a school teacher, but he later entered the Congregational ministry. He was pastor in several small Minnesota towns, so we moved about quite a bit.

The phosphate ore, or matrix, is a mixture of white pebbles of phosphate, of all sizes but mostly minus I to 1 1/4-in. diameter, in a matrix that varies from nearly all silica-sand gangue to a mixture of pebble, sand and clay. There is an occasional streak of hard pan of sand cemented with iron oxide, which can be drilled without much difficulty.

Activity-composition relations in Pt-Cr and Pd-Cr alloys of low chromium concentrations UCr < 0.3) have been determined in order to ascertain quantitatively the extent of reactions to be expected between Cr2O3-containing oxide phases and platinum or palladium crucibles used as containers in studies of oxide equilibria at low oxygen pressures. This work is a continuation of similar work previously

Encouraged by increased demand and higher prices for such metals as copper, lead, zinc, silver and tin, search was pressed in 1964 for mineral raw materials, especially in parts of the world that are relatively more stable politically and economically. New discoveries of metallic ores continued to be made, discoveries based on extensive geologic and geophysical work but nonetheless made in part because of good fortune.
