The O product series shares the same leaching process and flowsheet as cyanidation. Ecogoldex O product series can replace cyanide in gold ore mine flowsheet (Heap leach, CIL/CIP) seamlessly without any circut change or equipment modifiion. The E series stripping/recovery process is as simple as step 1,2,3. This process can be described as:
The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ''see'' the gold in the leaching process.

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to

Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process.. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process. As such it is used in most industrial appliions where the presence of competing silver or copper does not prohibit its use.
African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation. The ore is first reduced in size (typically 80% passing 75µm) to ensure that all nonrefractory gold is readily accessible for cyanide leaching. There are several variations of comminution circuits used in the
