Popular Applications for Log Washers. Log Washers are widely used for washing materials, including hard rock ore, gravel, limestone and phosphate, that have tough, plastic sticky clay contaminants. Feeds having up to 15% clays can be removed in a single unit. The largest feed size can be up to 150mm or 6".
construction, the hard rock mining industry has always shown a major interest in the use of TBMs for mine development, primarily for development of entries, as well as ventilation, haulage and production drifts. The successful application of TBM technology to mining depends on the selection of the most suitable equipment
Choice of particle size analysis technique is a function of the goals of the analysis. Many of the particles encountered in mining are characterized by sieves (classifiers). These are screens with a known opening (mesh) size. Particles smaller than that mesh size will pass .

Or B = 25D to 30D for hard rock B = 30D to 35D for medium rock B = 35D to 40D for soft rock Spacing (S) : This is the distance in metres between adjacent blastholes and is measured perpendicular to the burden. Usually the relation between drilled burden and spacing is: S = 1 to The above definition is best described by the Figure 1.
Hard Rock Miner''s Handbook is a work of the heart. Jack—whose 40+ year career spanned engineering, construction, and operation of mining projects worldwide—conceived of and wrote the first edition of the Handbook, published in June 2000, to assist miners and engineers in the difficult world of hard rock mining. It was his

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.

HPGR or highpressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.
capacity and size. If an increase in production triggers a change in employment levels, an amendment to SMC''s East Boulder Hard Rock Impact Plan would have to be approved before the action could be put into place. The purpose of this action is to allow SMC flexibility in production as changes occur in the market and grade of the ore encountered.
