tank leaching process

Introduction of Vat-LeachingVat leaching has been around since Roman times, but had become viable in 1896, when cyanide leaching began in earnest with the Merrill-Crowe Process.In an article in the Engineering and Mining Journal in December 1999, Lou Cope described the first vat leaching at Homes take in 1901, which later improved the process in 1906 by adding a desliming circuit

    Gold tank leaching process is applied in dealing with fine grained gold or gold tailings, generally on a small scale. Technology Advantage. Cyanide tanks are the main facilities for tank leaching process, which are often in rectangular shape. The size and quantity of the cyanide tank are based on the capacity, local conditions and leaching time. After construction, the work flow is loading, leaching, discharging

    In tank leaching the material is ground sufficiently fine to form a slurry, which can flow under gravity or when pumped. In vat leaching typically a coarser material is placed in the vat for leaching, which reduces the cost of size reduction.Tanks are typically equipped with agitators, baffles, gas introduction equipment designed to maintain the solids in suspension in the slurry, and achieve leaching

    Leaching is carried out by two main methods: simple leaching at ambient temperature and atmospheric pressure; and pressure leaching, in which pressure and temperature are increased in order to accelerate the operation. The method chosen depends on the grade of the feed material, with richer feed accommodating a costlier, more extensive treatment
