Sep 01, 2009 Initially, the effect of particle size of ore on the leaching process was studied using 3 M FeCl 3 at 80 °C with a liquid:solid ratio of 1.2:1. Batch tests were carried out for 6 h on various particle sizes of ore ranging from 20 to 170 mesh number (88 to 840 μm) with an A.S.T.M. series of trays and the results are shown in Fig. 1.Since over grinding of the ore may bring about troublesome

Uranium processing Britannica

Uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.

Vanadium processing, preparation of the metal for use in various products.. Vanadium (V) is a grayish silver metal whose crystal structure is a body-centred cubic (bcc) lattice, with a melting point of 1,926° C (3,499° F). The metal is used principally as an alloying addition to high-strength low-alloy (HSLA) steels and, to a lesser extent, in tool steels and iron and steel castings.
