Our History

Yuba Mining and Machine LLC is a full-time, dedicated mining equipment manufacturer specializing in gold processing and recovery. Our team has over 50 years of combined experience in the precious and base metals mining industry. We work closely with each of our clients to ensure the successful recovery of your targeted materials—from raw ore to refined gold bars. What sets us apart from other mining equipment manufacturers are our two unique, field proven concentrators: the Reverse Multi-Helix Spiral and the Horizontal Low-G Centrifuge. The Multi-Helix Spiral was first developed in the late 1970s as a cleanup concentrator. In the early 1980s, we introduced the Low-G Centrifuge as a primary gold concentrator designed to complement the Multi-Helix Spiral system. Together, these two technologies provide unmatched recovery performance—capturing more gold and other minerals than previously thought possible.

Our equipment is proven effective across a wide range of ore types, from alluvial gravels to finely milled hard rock. Minerals and metals we commonly concentrate include: mercury, galena, sulfides, pyrites, tin, copper, chromite, iron, PGMs, and more. Nearly any material that can be recovered by gravity concentration can be processed with our systems.

​

All of our recovery methods are chemical-free and environmentally friendly—offering a clean, efficient solution for modern mining operations.

All of our equipment is proudly manufactured in the USA.
