The Keene Cyclone Gold Sieve/Classifier is a fast, efficient, and easy-to-use classification system designed to help prospectors process material more effectively and improve overall gold recovery. Featuring three interchangeable mesh sizes — 2 mesh, 4 mesh, and 12 mesh — this versatile classifier allows you to quickly separate material into consistent sizes for panning, sluicing, highbanking, dredging, and fine gold clean-up operations.
At High Plains Prospectors, we know proper classification is one of the most important steps in successful gold recovery. Removing oversized material and sizing concentrates correctly helps recovery equipment perform more efficiently while increasing your chances of capturing fine gold. The Keene Cyclone Sieve system is designed to make that process faster, cleaner, and more productive both in the field and at home.
Built with durable construction and designed for serious prospecting use, this classifier system is ideal for processing creek gravels, pay dirt, concentrates, black sands, and material from sluices or dredges.
