Precious Metal Refining

The process takes place inside a work tank which is placed strictly under the hood and under suction, housed also on the upper floor of the building structure. This will allow, with some modifications, to discharge the liquid of the saturated solutions, inside the crystallization system, which will be placed under them and therefore on the lower level. This crystallizer is wheeled and equipped with a Buckner filter for collecting gold salt.

The work tank will also be equipped with a movable lid, with tilting opening and connected separately to a reflux head in glass, for the condensation of the produced vapors, which will consequently be directed inside the tank to which they are bound. This system avoids decreases in volume in the tank and therefore negative variations in the concentration of the salt in solution, thus automatically guaranteeing the right final title.

Downstream of the process, a liquid treatment system is envisaged for immediate recovery of the residual gold.

Now a days e waste materials are resulting into heavy pollution that can be harmful. But we at delmer are converting the e waste into a useful products.. we are recycling the e waste and producing mining machines which help you the mine the gold. They are made of super quality with less pricing which can be affordable for all

Increasing global technological development has immensely resulted into enhancing production of electronic waste that creates the challenges and opportunities in its recycling. In this review, we focus on the core value of metal resources in the printed circuit boards usually found in end-of-life electronics, the differences between primary mining applications and secondary mining, and the variety of metallurgical separations, in particular those that have the potential to selectively and sustainably recover gold from waste PCBs. It’s a very reliable and sustainable method which can be very useful for electronic waste and can result into a beneficial product

We at delmer provide these products which can to decrease the pollution and can be beneficial to customers.

"THE BENEFITS OF RECYCLING TECHNOLOGICAL WASTE According to research and facts , it is 13 times more costly to extract minerals from natural deposits than it is to recover them from technological waste for the manufacture of new devices. Obtaining minerals like platinum, copper and palladium does not just involve digging them up and processing them, it also requires the use of huge quantities of water and energy. This is where the concept of the circular economy comes in, based on the use of materials from recycled items and less dependence on the virgin resources extraction."
