Synthesis of grinding time-size reduction relationships
By P. C. Kapur
Several empirical and semi-empirical laws of comminution, which describe the relationships between the cumulative grinding energy input and the degree of size reduction of brittle solids, have been ra

Types of rock encountered in mining on the Witwatersrand and their mineral constitution
By R. J. Bridges
Mining operations on the Witwatersrand are conducted for the most part in rocks of highly quartzitic character. They comprise the following types: Conglomerates, grits, and quartzites, to which on the

High-speed air-compressors for mining work, paper presented at a general meeting of the North Staffordshire Institute of Mining and Mechanical Engineers held in Stoke-on-Trent, 17 January 2016
By Walshe J. M.
The slow-speed compressor is giving place to the high-speed type, with its greater economy of material and space; and, where very large units are required, the turbo-compressor is supplying the need.

Petrography and paragenesis of platinum-group minerals in Jinchuan ultramafic intrusion, northwest China
By Li Shibo, C. Halls
The compositions of olivine, pyroxene and chromite from the Proterozoic ultramafic complex are analagous to those of cumulate ultramafic rocks of tholeiitic origin, suggesting that the parent magma ma

Pit-timber and its preservation.
By Groom P.
The wastage of timber in coal-mines that is caused by decay is very great; in fact, far greater in this country than is generally realized. Mr. E. W. Peters estimates that of the whole wastage of timb
