The operations are designed in such a way that raw materials can enter the flowsheet at the most optimal process step, determined by their physical aspect, their analytical fingerprint and their (precious metals) value. The smelter furnace (first step in the Precious Metals Operations) uses the Isa smelt, submerged lance combustion technology.
The different flowsheets for the roasting process are influenced by operating temperature for maximum gold recovery, oxygen concentration in the roaster off gas, impurity control in calcine product and off gas, requirements for heat recovery, and finally the CAPEX aspect, with the goal being to develop the most economical flowsheet possible.

The washed residue would be pumped to the tailing pond. The gold and silver in the filtrate solution would be precipitated with zinc dust and the barren solution recycled in the usual manner. The gold-silver precipitate, containing 95% of the gold and silver, would be fluxed and melted and cast into dore' bullion bars.

Gold Flowsheet No. 3 indicates the addition of a required mill, classifier and extra "Sub-A" Flotation cells to provide for an increase in capacity and improvement in recoveries by regrinding of middling products. Gold Flowsheet No. 4 shows an increase in flotation capacity to further improve recovery. The additions as illustrated allow an ...
It has been said that gold was one of the first metals to be mined. As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore.

In Kosaka Smelting and Refining Co., Ltd., tin input increases rapidly from around 2008, because of TSL furnace starting up and raw materials change from ores to E-scraps. With tin increase, more dross was produced in lead purification process, and the dross became deadstock. ... In the purification process, gold, silver, and other valuable ...
The cyanide is regenerated as free cyanide and recycled to the gold extraction circuit. We have designed and constructed full-scale plants, provided process review and commissioning for a plant under construction, and carried out flowsheet development and testing programs for SART.

Many of our so-called small gold mines or low grade deposits could well take this simple and inexpensive flowsheet for an example and be rewarded by a good profit per ton of ore treated, if the owners or operators would adhere to these principles.
What Is Smelting? Many people confuse gold smelting and melting. While melting entails heating the gold from solid to liquid form before forming gold bars, the smelting process is more complex and involves removing impurities from the gold using a combination of pressure, heat, and several chemicals.

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return.This latter point is most important. …
and smelting. In the latter case, gold credits are obtained from smelting the copper concentrates and if gold reports to the flotation tailings, they may also require cyanidation which can prove problematic with cyanide soluble copper. MINERALOGY Gold occurs typically as metallic gold, sometimes as electrum and can also occur in pyrite
The conventional treatment of copper–gold concentrates involves smelting, converting and electro-refining to produce a copper-cathode product. Sulfur in the copper concentrates is oxidized to sulfur dioxide during smelting and converting and is normally used to make by-product sulfuric acid. ...

The message "Avan takes your gauntlets, takes out a small hammer, and pounds them into a slightly new shape, then hands them to you." appears as this happens. The Goldsmith gauntlets increase the experience gained from smelting gold ore into a gold bar, from 22.5 to 56.2 experience — about 2.5 times as much as without the gauntlets.
