Leaching Recovery of Zinc, Cobalt and Manganese from Zinc Purification Residue

This paper reports on the recovery of zinc, cobalt and manganese by two-step leaching of zinc-plants purification residue with sulfuric acid. The residue, hot filter press cake (HFC), contains 14 % ZnO, 4.8 % Co3O4 and 22.9 % MnO. Effects of different parameters are determined and used to optimize the process. With acid to hot filter press cake (HFC) stoichiometry of 0.85, acid concentration of...

Stress-strain relations for crystals containing plastic deformation.

Let P be one of the possible slip planes in a crystal, and let X be one of the possible slip directions in the plane P. Also let S be the magnitude of the shearing stress on the plane P resolved in the direction X, and So the critical value of S, i.e., the least value of S sufficient to permit slip or plastic deformation under the conditions specified in the following italicized statement; if s...

New Thermomechanical Reciprocity Relations With Application to Thermal Stress Analysisi

Based on the variational formulation of linear thermodynamics as developed previously by the writer, thermomechanical reciprocity relations are discussed which lead to new methods of analysis of thermal stresses. These reciprocity relations are quite different from the usual ones derived from the analogy of thermal loading with a combination of surface and body-force distribution. The results a...

Stress-Strain Field and Theoretical Analysis of RC Bridge

In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...
