Industry:Mining
Catchment to which spillage can gravitate should it be necessary to dump the contents of mill machines such as classifiers, thickeners, and slurry pumps. Provided with a reclaiming pump so that the contents can be returned to the appropriate part of the flow line.
Industry:Mining
Cement stone band. Stone suitable for coinstones, quoinstones, and cornerstones, used in building.
Industry:Mining
Cement to which a small percentage of bentonite has been added either dry or mixed with water. Such an addition particularly adapts the slurry for use in cementing casing and recovering lost circulation because it reduces loss of slurry to the formation, makes for a more homogeneous mixture, increases the water-cement ratio, reduces loss of water to the formation, and sets in substantially the same volume as occupied when placed.
Industry:Mining
Ceramic product made from any of the pure oxides of nonmetallic materials; i.e., Al<sub>2</sub>O<sub>3</sub>, MgO, SiO<sub>2</sub>, etc.
Industry:Mining
Cerium alloy (55% to 65%) containing rare-earth metals and iron.
Industry:Mining
Certain minerals that have a fibrous structure, are heat resistant and chemically inert, possess high electrical insulating qualities, and are of sufficient flexibility to be woven. The two main groups are serpentine and amphiboles. Asbestos proper is actinolite. Chrysotile is fibrous serpentine; amosite is fibrous anthophyllite; crocidolite is fibrous soda-amphibole. Used in fireproof buildings, insulating, paint materials, brake linings, and clutches, and as insulation against heat, electricity, and acid.
Industry:Mining
Certain minerals usually associated with diamond, such as ilmenite, garnet, zircon, rutile, corundum, spinel, olivine, and gorceixite.
