May 13, 2013 · Vat leaching can be described as leaching in a bathtub inside a building. Treatment of ore is site-specific as determined by metallurgical tests. Bench scale metallurgical testing of ores for their amenability to vat leaching is similar to that for heap leaching. First, bottle-roll tests of finely ground material are run to determine the ultimate recovery of gold…预计阅读时间：3 分钟
Leaching (Gold Dissolution) Once Vat is loaded with ore, is flooded with a leaching solution of a desired cyanide concentration (usually 600 to 1000 ppm) and pH between 10 to 11 at ambient operating conditions through the filter section of the floor or added to the top of the ore charge.预计阅读时间：10 分钟
Nov 02, 2016 · Leaching Gold in Vat The crushed ore is conveyed in cars pushed by hand, running on an overhead railway, and emptied into the vats by tipping. The supports of the railway must not touch the sides or any part of the vats or their supports, as the jarring caused by the running of the cars makes the ore settle down, and so renders the leaching more difficult and tedious.
Jul 13, 2016 · Vat Leaching of Finely Crushed Gold Ore. Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of well-mixed neutralized sand, ample …
Jun 05, 2020 · Gold vat leaching process has certain requirements on the temperature. Figure 1 shows the relationship between the dissolution rate of gold in sodium cyanide solution and temperature. Generally, the temperature at 15-20℃ can meet the vat leaching requirements.
Feb 15, 2020 · Tank and vat leaching involves placing ore, usually after size reduction and classifi ion, into large tanks or vats at ambient operating conditions containing a leaching solution and allowing the valuable material to leach from the ore into solution. In tank leaching the ground, classified solids are already mixed with water to form a slurry or pulp, and this is pumped into the tanks.
The Iwato ore is gold and silver bearing silicified porous rock. As most gold and silver in the Iwato ore are concentrated in the pores, leaching of coarse sized ore is expected to be possible. Laboratory tests and pilot plant tests of vat leaching for the Iwato ore were carried out using 0.15-8.0 mm feed.
