Book Description
Handbook of Flotation Reagents: Chemistry, Theory and Practice is a condensed form of the fundamental knowledge of chemical reagents commonly used in flotation and is addressed to the researchers and plant metallurgists who employ these reagents. Consisting of three distinct parts: 1) provides detailed description of the chemistry used in mineral processing industry; 2) describes theoretical aspects of the action of flotation reagents 3) provides information on the use of reagents in over 100 operating plants treating Cu, Cu/Zn, Cu/Pb, Zn, Pb/Zn/Ag, Cu/Ni and Ni ores. * Looks at the theoretical aspects of flotation reagents * Examines the practical aspects of using chemical reagents in operating plants * Provides guidelines for researchers and engineers involved in process design and development

Book Description
"Flotation is a new step in the separation of valuable minerals from gangue. This process has only been in commercial use for about six years. There has been several theories advances as to how the ore is concentrated, and the theory that is now usually accepted is that the oil covers or wets the sulphide mineral particle and does not the gangue; and this mineral particle, by means of induced aid is concentrated on the surface. The authors of this thesis have not attempted to explain the reason or reasons why minerals will float; but have accepted the theories advanced by men far more capable, but we have worked on the assumption that sphalerite, the sulphide of zinc, according to all flotation theory will float, so our problem narrowed down to one fact which can be stated in the one word - How"--Leaf 1.

Book Description
Excerpt from A Manual of Flotation Processes Flotation concentration includes within its scope almost as many processes as all other methods of ore concentration combined, the only elements common to all the processes being selection, or concentration, and separation of the concentrate from the tailing by flotation of the former. Widespread understanding of the physical principles underlying flotation phenomena and of the diversity of flotation processes has been delayed for divers reasons. The apparent complexity of the phenomena and the difficulties of investigation are sufficient to explain some of the delay, but much of it is chargeable to the stand of patent-owning corporations in their attempt to establish a monopoly on flotation processes. These companies have steadfastly opposed dissemination of knowledge of the art by their employees and licensees, notwithstanding the moral and legal duty of a patentee to make full and truthful disclosure of all he knows concerning the subject matter of his patent; by threats of litigation sown broadcast they have succeeded in causing a veil of secrecy to surround the operations of non-licensees; and by their unfounded claims that all flotation processes prior to that described in U.S. Patent 835, 120 were laboratory curiosities or commercial failures, and that those subsequently discovered were merely improvements of that process, they have caused the spread of wrong ideas on the part of many of those interested.

Book Description
"The problem of the Mining Engineer and Metallurgical Engineer who wishes to treat the slimes and fine sands of a complex ore is the recovery and separation of minerals so as to render a subsequent treatment of any mineral profitable. The minerals must be separated into groups which can be treated by different processes, because a combination of numerous minerals is extremely undesirable at the smelting plant. In a lead ore the presence of zinc often depletes its value to such an extent that it is unprofitable to treat it; likewise with other minerals and ores. Many systems of selective separation of slimes and fine sand have been tried but with little success. The latest attempt towards this end has been by means of the flotation process. The eagerness to separate the minerals of a complex sulphide ore is seen in a retrospection of the great number of patents that have been issued. These patents bring into consideration, a vast number of chemical solutions which are used as selectors in the flotation process. The object of our experiment work was to find the best method of selective flotation adaptable to a particulate ore at hand"--Introduction, leaf [3].
