Determination Of Critical Point Of Concentrating Tables On Flat River Ore, J. C. Finagin Jr., W. C. Hogoboom
Determination Of Critical Point Of Concentrating Tables On Flat River Ore, J. C. Finagin Jr., W. C. Hogoboom
Bachelors Theses
"In concentrating any ore on tables there is, theoretically, a critical point in sizing, beyond which it can not be expected to recover the valuable minerals; that is, valuable mineral finer than a certain size will go with the gangue and be lost. for instance, in the diagram of the Wilfley Table shown, the concentrates grade from coarse to fine as indicated, but instead of grading on down into very fine sizes farther up the table these finer sizes are found mixed with the middlings, tailings and slimes as indicated by the arrows. The problem is to determine the critical …

Bachelors Theses
"One of the principal disadvantages attending the use of most of the usual solvents for Copper, such as Sulphuric Acid, Ferrous Chloride, etc., in the treatment of tailings products, is that the solvent is not regenerated upon precipitation by iron, and in fact is destroyed by the precipitant. This of course involves a dead loss of a definite portion of acid or other reagent, proportional to the amount of Copper dissolved. A solvent which would be regenerated upon precipitation is eminently desirable. At the same time, a carbonate gangue, or one of such a nature which will react with the …
