Cone Crusher Installation
Tabulated installation drawings show the principal dimensions of the Hydrocone cone crusher, and are sufficiently accurate for preliminary plant layout work. In the smaller sizes (up to 48-in.) the Hydrocone crusher can be discharged vertically downward, or a feed spout can be provided which will convey the crushed product off to one side. Rubber shear mountings […]

Hydraulic Gold Mining
Hydraulic Gold Mining is the cheapest form of gold mining is that in which the precious metal can be removed from its associated impurities—such as clay, gravel, sandstone and iron—and collected, entirely by the agency of water and mercury, with a minimum of manual labour. This can be done where there occur high banks of […]
Dredge Construction
Dikes for River Control.—Dredging and the maintenance of dredged depths is intimately related to the subject of the characteristics and regulation of rivers. This, however, is much too broad and far reaching in its scope to be included within the narrow confines of this small book, and will merely be summarized with maximum brevity in […]
SEA Floor Mining
Introduction Ocean floor mining encompasses the extraction of valuable resources from the ocean floor, utilizing advanced technologies and methods designed to operate in challenging underwater environments. As demand for these resources increases, innovative solutions are vital for efficient extraction. Technological Innovations Modern ocean floor mining relies on cutting-edge technologies such as remotely operated vehicles (ROVs) […]
Hydraulic Dredges
There are two general and distinct classes of hydraulic dredges, the River Type and the Sea-going Hopper Dredge. The first is the smaller machine, built for use in the calm waters of rivers and sheltered harbors, and is rarely self-propelling except among those designed by the Mississippi River Commission to meet the special and unique […]
Dipper Dredges
General Description.—As has been said, the Dipper Dredge “ digs ” like the familiar steam shovel. The bucket, which is essentially a scoop with heavy teeth and a flap bottom, is attached to the end of the dipper stick, which is carried by the boom at or near the centre of the latter. The boom […]
Grapple Dredges
General Description.—A grapple dredge is, in principle, a derrick mounted on a float and swinging a grab bucket. Any derrick lighter may perform the operation of dredging by simply attaching a grab bucket to its fall. This, however, is merely a makeshift, and by no means constitutes a dredge. The operation of the bucket is […]
Gold Dredging & Sluice Box
The Metallurgy of Dredging: The gold-saving appliances of a dredge consist respectively of screens, tables, and sluices. The essential duty of the screen is to classify the material prior to concentration, it also serves to disintegrate or break up the material passing over or through it, so that particles of gold may not be carried off […]
