Technical Service

We provide a superior technical service through:

Onsite service–as directed by our client, we send our expert to the client’s site to supervise the use of EarthGold GLR to help our client get the maximum benefit from the application of our EarthGold gold and silver leaching reagent.

Contracted service – For specific leaching process operations, especially for difficult-to-treat ore with sound grade, a client can contract our services when they have an existing leaching process using cyanide and the client wants to increase output and reduce the environmental impact then this mode is able to be applied. In contract mode, we test about 10kg sample of the ore and an additional 1-2kg of cleaned ore. Depending on the results, we then design a leaching process that may include small modifications to the existing equipment and processing plant. We send experts to the client’s site to supervise the execution of the designed process to ensure the agreed target is reached. We provide onsite training to ensure site people can operate the process correctly. In general, this service allows the client to optimize their gold and silver leaching process to raise output and save cost.

Through our technical service, the leaching rates can be significantly increased and leaching time can be certainly shortened 50% by using EarthGold 600, see below comparison form.
