Available in PDF, EPUB and Kindle. Book excerpt: The results are presented of several small-scale pilot-plant investigations that demonstrate the feasibility of a resin-in-pulp process for the combined extraction on gold and uranium. Both metals are leached into an aqueous solution as anionic complexes, and under appropriate conditions, both metal anions can be stabilized in the same solution and extracted from that solution by anion-exchange resins. Three different feed materials containing gold and uranium were tested, and several configurations for leaching and the resin-in-pulp process were examined so that the efficiency of extraction of the process could be demonstrated. The results of the various pilot-plant investigations are discussed, with particular emphasis on the deportment of gold and uranium during the leaching, extraction, and elution steps.

This book was released on 2008-10-01 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pines are known to mankind from the time immemorial. It offers both direct uses, as well as indirect uses specially soil conservation. Initially it was used mainly for fuel; their branches were used for festivals etc. Pines besides being a source of valuable timber, pulpwood, yield pitch, tar, rosin, colophony and turpentine, collectively known as naval stores, a term coined to these owning to their use for construction and maintenance of sailing vessels as sealing compounds for their wooden hulls. The genius pine species tapped for their oleoresin in different countries. A variety of oleoresins are extracted from various plants. Pine oleoresin being the most important one is extracted from pine trees. Turpentine and rosin are two constituent parts of the pine oleoresins. The composition of turpentine varies considerably according to the species of pine exploited. More and more specialised uses are being found for pine resin products, particularly those of high quality. Turpentine derived from pine resin is also used as a source of aroma chemicals in flavour and fragrance industry. Pinewood chemicals are effectively gained from the trees in three principal ways; treatment of exuded gum from living pines, processing the wood stumps and wastes of aged trees and treatment of black liquor obtained as a byproduct in wood pulp industry. There are two steps involved in production of oleoresin; olustee gum cleaning process and recovery of turpentine and rosin: batch and continuous process. The panorama of base catalysed isomerisations of terpenes is an important part of aroma chemistry. Major contributions in this area are presented here under sections on hydrocarbons, alcohols, aldehydes, ketones, acids, esters and epoxides. Tall oil is a by product of the pine wood use to make sulfate pulp. Tall oil products find use in many product applications because of their economy and ready availability. The principal industrial applications of tall oil products are numerous; adhesives, carbon paper, detergents, driers, drilling fluids, oils, gloss oils, paper size, plasticizers, printing inks, soaps, textile oils etc. Some of the fundamentals are pine oleoresin extraction methods, occurrence, formation and exudation of oleoresin in pines, processing of oleoresin, rosin derivatives and its potential, new developments in rosin ester and dimer chemistry, terpene based adhesives, effect of solvent, ozone concentration and temperature on yields were investigated, sylvestrene and some of its derivatives, homopolymers and copolymers of acrylates, polymers and copolymers of vinyl pinolate, base catalysed isomerisations of terpenes, components of pine roots, insecticides based on turpentine, the general characteristics of dimer acids, structure and properties of dimer acids etc. The present book has been published having in views the important uses of pines. The book contains manufacturing process of different products extracted from pines like oleoresin, rosin, turpentine derivatives, tall oil, resins and dimer acids etc. This is the first book of its kind which is very resourceful for all from researchers to professionals.

Download or read book A Resin in pulp Process for the Recovery of Copper from Bioleach CCD Underflows written by and published by . This book was released on 2001 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resin-in-pulp (RIP) process was developed primarily for the recovery of metals from high volumes of low-grade pulps, as is the case in the gold processing industry. However, this technology can also be applied to the recovery of soluble metals from solid residues on base metal plants. Applications for the RIP process include the scavenging of valuable metals from leach and precipitation residues, especially where the solids have poor filterability of settling characteristics. The RIP process will improve overall plant recoveries, and it may be possible to decrease the filter duties of the degree of washing on the filters. In addition, the barren stream from the RIP operation may reduce any environmental impact significantly.^L^LBilliton Process Research (BPR) commissioned Mintek to investigate the metallurgical and economic feasibility of a resin-in-pulp process for the recovery of copper from bioleach counter-current decantation (CCD) underflows. Batch laboratory testwork and a continuous mini-plant campaign was conducted in order to optimise the process parameters. The results were used to conduct a preliminary sizing and costing study, in order to evaluate the economic viability of the RIP technology for this application.

Book excerpt: Resin-in-pulp (RIP) technology has been developed for recovery of gold. It is now time to look forward to the potential for application of the technology to other situations. Some cases have been identified and have merited preliminary testwork. Four examples, which illustrate the potential of RIP, are dealt with in this paper. These include removal of metal-cyanides from pulps, recovery of manganese that is difficult to wash from filter cakes, recovery of nickel from low grade pulps, and recovery of zinc from process residues. The discussion includes descriptions of the problems, factors that affect the choice of resin, and factors that will affect the economics of the process. (AUAB).
