The Mineral Industry Its Statistics Technology and Trade During 1921 Vol 30 by G. A. Roush Book PDF Summary
Excerpt from The Mineral Industry, Its Statistics, Technology and Trade During 1921, Vol. 30: Supplementing Volumes I to XXIX A number of minerals of lesser importance from a technical standpoint have not been covered in this work. This applies in particular to those connected with the pottery and building trades, whose raw materials are so widely distributed that a general report would require space out of all proportion to its value in a review of this kind. On the other hand, some industries relating to manufactured material are included, when the product is directly dependent on the production of raw minerals, or where it is being substituted for them, as in the case of cement and coke.
