[0002] When the natural copper content in the copper sulfide ore is high, especially the copper ore with high natural copper content in large pieces and coarse particles, the crushing of the original ore containing natural copper and the recovery of natural copper after crushing are all faster than the conventional copper sulfide ore. The grinding-flotation method is more complicated. Due to the good ductility of copper, when the traditional cone crusher is used for the second stage of crushing, large pieces of natural copper are easily pressed into flakes and adhered to the crusher. In the crushing cavity, it will cause damage to the crushing equipment and affect the normal production and operation.
On the other hand, due to the fact that natural copper may adhere to the liner in the process of semi-autogenous mill and ball mill, and accumulate in the mill and cannot be discharged, resulting in blockage of the entire production process

Embodiment Construction
[0016] The beneficiation process of high-grade natural copper-containing copper sulfide copper ore of the present invention comprises the crushing and recovery process system of large natural copper, the crushing process system before gravity separation, the gravity separation recovery process system of coarse-grained natural copper, the fine-grained natural copper The natural copper gravity recovery process system is composed of the natural copper gravity recovery process system and the copper sulfide ore recovery process system. The specific implementation process is as follows:
[0017] 1. Crushing and recovery of large pieces of natural copper: the raw ore is firstly crushed by the first jaw crusher, and the ore after jaw crushing is sent to the grading screen through the belt, and the -40mm ore under the screen is the crushed qualified ore, which is fed into the sieve. The second stage crushes the roller crusher. After crushing, the ore is fed to the third stage pre-crushi...

Abstract
A beneficiation process of high-grade natural copper sulfide copper ore, which recovers large natural copper ore with a particle size greater than 40mm in the crushing process; uses high-pressure roller mills to crush coarse natural copper with a particle size of less than 40mm-cylindrical concentrator + Vibrating sieve dispersing and classifying ‑ jigging + screw slide + shaker gravity separation recovery; gravity separation tailings (copper sulfide ore) are recovered by grinding and flotation. Using the beneficiation process of high-grade natural copper-containing copper sulfide ore of the present invention, high-grade natural copper can be recovered efficiently in advance, and copper sulfide ore and sulfur-cobalt ore can be recovered at the same time, which can overcome the damage of the crusher caused by the good ductility of copper And accumulate in the mill, so as to ensure the smooth operation of crushing and grinding production.
Description
technical field [0001] The invention relates to a beneficiation process of copper sulfide ore, in particular to a beneficiation process of high-grade natural copper-containing copper sulfide ore, which belongs to the technical field of beneficiation. Background technique [0002] When the natural copper content in the copper sulfide ore is high, especially the copper ore with high natural copper content in large pieces and coarse particles, the crushing of the original ore containing natural copper and the recovery of natural copper after crushing are all faster than the conventional copper sulfide ore. The grinding-flotation method is more complicated. Due to the good ductility of copper, when the traditional cone crusher is used for the second stage of crushing, large pieces of natural copper are easily pressed into flakes and adhered to the crusher. In the crushing cavity, it will cause damage to the crushing equipment and affect the normal production and operation. On t...
