Copper extraction - Wikipedia

A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock. The first stage of any process within a metallurgical treatment circuit is accurate grinding or comminution, where the rock is crushed to produce small particles (<100 μm) consisting of individual mineral phases.

The Maintenance, Repair and Replacement of Historic Cast Stone

Photo: Richard Pieper. The methods of composite repair used for stone masonry are also generally applicable for the repair of historic cast stone. For repairs to damaged cast stone to be successful, however, both the cement matrix color and the aggregate size and coloration must match that of the historic unit.

Exhibit 99.1 - SEC

Metallurgical holes were typically drilled using PQ size core (85 mm). Any break in the core made during removal from the barrel was marked with a "colour line". When breakage of the core was required to fill the box, edged tools and accurate measure of pieces to complete the channels was the common practice to minimize core destruction.

The requirement for treatment of water for re-use in metallurgical processes varies in accordance with the process flow-sheet involved. For example, fluoride-rich waters need to be avoided in some types of iron-ore plants, so RO is commonly used. Also, specific mineral processes such as flotation may require the removal of additional compounds.
