  • Gold Extraction &Recovery Processes

    Considering the different gold minerals present alone or combined with the host rock, it will be necessary to discharge the unwanted material in order to increase the concentration of gold in an economically manner. This part treats the strategy of beneficiation as a combination of several processes. Joining together these units make possible to develop an appropriate flowsheet whose objective is to recover gold and the precious metals present in the ore. Perhaps, one of the greatest challenges in the gold mining industry is to produce high grade concentrates consistently at maximum recovery from the mineralized deposit. To quantify recovery is a reasonable idea of the initial ore required to have an economical operation. In this part, a reliable sampling representing the ore is a key aspect. aration, concentration and leaching processes involve several operations such as screening, classification, solidliquid separations, gravimetry, flotation, and pregnant liquid solution trea

    The process to be employed must be selected considering several factors such as geology, mineralogy, metallurgy, contamination, location and profitability. 1. Geology At the beginning of any gold project, there are some questions that typically appear, one is related to the compositing schemes and is related to the ore body type, and second, the level of variability in the deposit. Both factors are influenced by geological considerations such as rock type, lithology and ore type. They are involved to the character of the rock described I terms of structure, mineral composition, particle size and arrangements. The single most difficult task in any project is the acquisition of an understanding of the mineralized deposit. In some cases, representative samples can be obtained by diamond drilling in a relatively tight pattern encompassing the mineralized zone. Drill core intervals are subdivided by lithological horizon and ore types composites are prepared. It is considered that a good

    Gold recovery comprises similar stages to the processing of most ores. First, the valuable minerals are separated from the gangue through concentration. The final concentrate is obtained by repeated processing and is smelted or leached in order to get a Dore bar. In generals, the concentration of gold includes three stages: roughing, cleaning and scavenging. The reason of concentration is to separate the raw material into two products, concentrate and tails. Ideally, in free gold recovery, all the gold will be in the concentrate and the other part will be in the tails. arations are not perfect and in practice some waste material is reported into the concentrate and some gold particles remains in the tails. Intermediate products are called middlings and can be defined as particles that belong in either the concentrate or tails. Sometime, this product is a serious problem. Roughing can be considered as the upgrading of the ore to produce either a low grade, preliminary concentrate

    Amalgamation is one of the oldest methods of extracting gold from its ores. The amalgamation of gold possibly dates from Roman times. The extraction of silver by amalgamation is generally attributed to the Spanish in Latin America in the late sixteenth century even though Biringuccio describes the fundamental principles of the patio process about a half a century earlier. The amalgamation of gold ores as described by Agricola in De Re Metallica is essentially the same as modern practice. The only changes are in the equipment employed and the sources of power to grind, mix, and separate. Probably, the chemical and physical processes are more clearly understood. Mercury is a heavy metal with specific gravity of 13.5, is liquid and boils at 357 oC. Its vapor pressure is low and can be in vapor state easily. Amalgam is an alloy between gold and mercury. There are three types of amalgams to be formed, AuHg2, Au2hg and Au3Hg. The content of mercury in the amalgams depends on two factors

    Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 250 µm. This process recovers fine particles of free gold, gold associated in any form with sulphides, and native gold present in polymetallic deposits with certain degree of oxidation. For many years, a combination of amalgamation, cyanidation and flotation made possible to get high gold recoveries. With the time the technology and design consideration changed and flotation and/or cyanidation processes are the favorite combination. When gold is recovered by flotation, a high grade concentrate contains gold and can give an extra value to copper and lead concentrates. The concentrate can be ground, roasted, treated by cyanidation and the final product is gold bullion. Considering the fact that native gold and electrum have variable composition and different parts of the same particle could present different composition, the recoveries of thes

    Cyanidation

    When we have to mention hydrometallurgical treatments, the cyanidation process must be mentioned initially due to has been employed in the gold mining industry for a long time. The cyanidation process was invented in 1887 when the gold recovery started to have some problems due to the lack of good technology. Basically the process is supported by two facts, gold is soluble in dilute solutions of cyanide, and second, the pregnant solution can be processed successfully by using zinc powder or a
