JXSC' gold mining solutions design allows you to start recovering minerals with a base wash plant (scrubber / concentrator) unit. Various crushing, milling equipment can be ordered to make your solution more comprehensive. This can be implemented at a later stage, once you have begun to see an initial return on investment. This way, JXSC provides miners with a low capital starting point.
