Below, fall scene in Wyoming's<br />

rugged Wind River Mountains,<br />

at the site of the<br />

Columbia - Geneva Division's<br />

"Atlantic City Project"<br />

for the mining and beneficiating<br />

of low-grade iron ore.<br />

This project will include an<br />

open pit iron ore mine,<br />

crusher, concentrator, pelletizer<br />

and shipping facilities.<br />

The raw materials program was further advanced in 1960 by the continued<br />

construction of iron ore production facilities at Quebec Cartier Mining<br />

Company in Canada. The construction of a major iron mining and ore beneficiating<br />

facility near Atlantic City, Wyoming to supply iron ore to the<br />

Columbia-Geneva <strong>Steel</strong> Division was also authorized. A new raw materials<br />

research laboratory for studying problems related to iron ore beneficiation<br />

was established by Columbia-Geneva. In addition to the present plant in<br />

Minnesota now being used for process development through the production<br />

of a limited quantity of commercial ores from low grade magnetic ore bearing<br />

materials, construction was authorized for an additional plant in Minnesota<br />

for experimental processing of non-magnetic low grade iron bearing<br />

materials which exist in substantial quantities in the western Mesabi Range.<br />

Better methods and processes<br />

Many people think of a steel mill as a series of large furnaces in which raw<br />

materials are melted, while nearby are the buildings that house massive<br />

machines to squeeze, shape, roll, or otherwise form the steel into various<br />

familiar products. But production of consistently high quality steels requires<br />

much more than that; it requires a multitude of necessary supporting equipment.<br />

Facilities are needed both for heating and for cooling the steel slowly<br />

or rapidly as required; machines are necessary for stretching, straightening,<br />

flattening, sawing, or cleaning it. But most important in producing high quality<br />

steels is the accumulating store of knowledge from which can be known in<br />

advance what will happen to the uniformity, structure and strength of the<br />

steel as various operations are performed.<br />

As an important research tool with respect to the efficiency of producing<br />

iron, a versatile four-foot diameter highly instrumented experimental blast<br />

furnace is being constructed which will accurately duplicate all phases of blast<br />

furnace operation. It will be equipped for precision control of temperature,<br />

pressure, wind velocity, and fuels. With it, furnace and supporting facility<br />

designs, size of materials, and fuels can be tested. In addition, construction of<br />

an ultra-modern blast furnace, near Pittsburgh, has been authorized. It will be<br />

the largest iron producing facility in the Pittsburgh District and will be equipped<br />

for evaluation of numerous technological innovations.<br />

Unnoticed by the casual observer are the tremendous quantities and varieties<br />

of refractory brick used in a steel mill. The selection of the proper brick for<br />

each process means greater productive time, and therefore capacity, because<br />

of the longer periods between shutdowns for repairs and rebuilding. Research<br />

scientists, using modern research tools and advanced techniques, analyze,<br />

design, construct and test to destruction various brick and brick shapes to<br />

find the best one for each of the many processes using such refractory materials.<br />

Such research has resulted in very substantial savings.<br />

Research on the shaping of steel involves, among other things, the development<br />

of complex systems of machine control which are largely automatic.<br />

Such controls are incorporated in the design of new equipment and in the<br />
