A Study Of The Differential Seperation Of Galena And Sphalerite, Wilfred E. Nagel Jun 1949

The smelting of complex lead ores is a difficult operation, especially when they contain considerable amounts of iron and zinc. When these ores are smelted, all of the zinc, which is valuable and well worth recovering, goes into the slag. With the advent of the flotation processes, and the ability of these processes to concentrate the lead and zinc minerals into separate products, the smelting of complex lead ores was to a great extent simplified.

The factors that influence the choice of a method for treat­ment of an ore comprise the technical and economic limitations and advantages, derived in detail and balanced according to the exigencies of the particular situation.


Benefication Of An Oxidized Lead Ore From The Franklin Mine Lewis And Clark County, Jack D. Mclenegan May 1949

Benefication Of An Oxidized Lead Ore From The Franklin Mine Lewis And Clark County, Jack D. Mclenegan

Bachelors Theses and Reports, 1928 - 1970

This thesis is concerned with the beneficiation of an oxidized lead ore. Emphasis was placed upon concentration by flotation rather than by gravity methods, although some investigation was made with the Wilfley shaking table. The concentration of lead minerals received most consideration in the problem, but wherever possible attempts were made to increase the silver and gold concentration along with the lead.
