With the rapid development of the gold industry, as a special commodity - gold, has entered the circulation field, to achieve the market transactions. For most gold production enterprises, the ensuing problem is that the purity of gold products produced by the traditional smelting process can no longer meet the requirements of the trade. Here is a detailed introduction to the gold refining chlorination purification process, take a look at it.
Gold refining chlorination purification process.
High purity gold processing process: Acceptance of alloy gold → pulverization → sodium chlorate sub-gold → sodium sulfite reduction → sprinkling beads machine sprinkling beads → ingot casting machine ingots → finished gold ingots.
Sodium chlorate gold separation process
Drying: The sponge gold obtained after reduction is washed with hot water until neutral. And then dried by oven.
Medium frequency furnace melting and pouring block: The sponge gold after baking and drying is melted using medium frequency furnace, and then pouring block.
Sun bead machine quenching bead: add the gold nugget into the crucible of the bead sprinkler, melt it, and then use high pressure water to cool the gold water for granulation.
Drying and ingot casting: The gold beads obtained by the bead sprinkler are dried using the oven and then. The ingot casting machine is used to cast ingots. The production process of gold ingot adopts the advanced fully enclosed molten gold casting.
Process flow is: gold nugget → quenching bead machine quenching bead → gold bead → oven drying → weighing → ingot casting machine → Au-1 gold ingot (or five nine gold ingots).
The main equipment is: bead quenching machine, ingot casting machine, ice water machine and oven.
The above is all about gold refining chlorination purification, hope to help you, if you need or have other want to understand the content, welcome to leave a message to consult us Oh ~
