Summary:

A study was made of the process of radioactivation of particles by adsorption of tracers from solutions. Applications are discussed in the development of procedures for the concentration and recovery of minerals from ores. Methods used for tagging the mineral particles are reviewed. Special problems are considered which are encountered in the use of tracers in flotation circuits where several possibly conflicting surface reactions take place simult aneously and the tracer must not interfere with normal flotation conditions. In view of the fact that in flotation systems the ore slurries are mixtures of minerals, attempts were also made to find possible markers which would be taken up selectively by different minerals. The minerals studied included marmatite, galena, pyrite, cassiterite, silica, siliceous gangue, and sphalerite. Methods used to test adsorption rates are described. Data are presented graphically on the adsorption of copper, silver, zinc-65, silver-110, barium-14O, lanthanum-140, cerium-144, tin-113, and cesium-137 under various conditions of pH and concentration. Data are tabulated on the comparative adsorption by mill products of iron-59, cobalt-60, copper-64, zinc-85, silver-110, cadmium-115, cesium-137, cesium144, europium-152 + 154, and mercury-203.
