Diamond Placer Beneficiation Case in Changde City, China

Changde Diamond Mine Processing Plant is located in Changde City, Hunan Province, China, which is specialized in fine-grain sand beneficiation. The main gravity separation minerals include diamond, gold, zircon, boehmite, garnet, rutile, ilmenite, hematite, etc. The diamond grade of original sand is 1-6 mg/m³. In addition, gold, zircon, ilmenite content is high that can be recovered. Gold can be recycled by amalgamation equipment.

The diamond in deposits mainly ranges 1-4mm, and the crystal quality is better. Beneficiation process mainly adopts gravity separation, and the main beneficiation equipments are cylinder washing machine, single spiral classifier, the under-action diaphragm jig, side-action diaphragm jig, side-action diaphragm jig, screening machine, vibrating screen, flotation machine, amalgamation extinguishers with diamond recovery 98%.

It shows that pre-enrichment postlaminar can improve the non-grade sorting effects. Under the premise of ensuring the recovery rate and same water consumption, the fine mineral rate is only 1/3; After getting the same rate of fine mineral, water consumption can be reduced by half. In addition, it can improve the granularity of concentrate composition, and make the ore particle size composition similar with original ore.

Mineral particles are separated from each other by the difference of relative density, particle sizes, shapes and differenct moving speed and direction of the medium (water, air or other relatively high density liquid). Diaphragm jig beneficiation is widely used in the process of hematite, limonite, sand gold, manganese, tungsten, tin, tantalum, niobium, mercury, fluorite ore, barite ore, celestite ore and other metal and non-metallic minerals, can also be used to process metal smelting slag, to recover the alloy particles and recyclable substances.

The diaphragm jigging machine produced by Forui Machinery have 7 series covering more than 10 models. The biggest deal size of large grain separator jigger can be 50mm. Forui can do free beneficiation tests for customers with only 20kg samples, and you can see the dressing effect. Our professional and technical personnel offer beneficiation process design, and is responsible for equipment installation and commissioning for you.
