URANIUM-COPPER MINERALOGICAL CHARACTERIZATION OF

Keywords: uranium, copper ore, QEMSCAN, liberation, entrainment . INTRODUCTION . Uranium is a reactive element with a negative reduction potential of 1.38mV and frequently occurs as oxides and/or oxysalts, elucidating their high affinity for oxygen. For nearly all of theoxysalts, uranium is oxidized to the soluble hexavalent state (U. 6+) (Bowell

Preconcentration of Primary Uranium Ores by Flotation

Preconcentration of Primary Uranium Ores by Flotation by Burt C. Mariacher E XTRACTION of uranium from ores is being ac- complished by processes which, for the most part, subject the entire ore to acid or carbonate leaching. Ore deposits with a U,O, content below 0.10 pct U,O, are seldom considered suitable for treatment by leaching.

Selective dissolution of uranium from a copper flotation

Aug 01, 1986· The copper flotation concentrate produced from the Olympic Dam copper--uranium-- gold deposit in South Australia contains uranium associated with the copper sulphide and gangue minerals. Work with a copper concentrate in which the copper mineraliza- tion was of the chalcocite--bornite type has shown that 94--97% uranium can be dis- solved with

Studies of leaching of copper ores and flotation wastes

Feb 16, 2014· In Poland, there are significant deposits of copper ores. During the copper extraction, large amounts of flotation wastes are produced. In the ores and flotation wastes many other important elements are present. The main goal of this work was analysis of uranium content and to elaborate procedures for recovery of U from these materials. Two types of ores and four types of waste were

Possibility of uranium and rare metal recovery in the

Jan 01, 2016· Copper flotation waste, which is the product of the pyrometallurgical production of copper from copper ores, contains materials such as iron, alumina, calcium oxide, and silica. Copper flotation waste generally contains a significant amount of Cu together with trace elements of other toxic metals such as Zn, Co and Pb.

WO2011161650A1 Beneficiation of uranium from low grade

This invention relates to a froth flotation process to beneficiate uranium economically from both low grade tailings dump ores or high grade ores; by upgrading into a concentrate. The first stage is a sulphide flotation for pyrite recovery, followed by an oxide flotation for uranium recovery. The selectivity of the process for recovery of uranium in the concentrate is enhanced by maintaining
