Long processing copper ore prior Sichuan capacity of 100 tons / day, open two-stage crushing, grinding process some closed circuit grinding broken ore.
Flotation is made with quicklime, Dinghuang and Yihuang (1:1) as collectors, and 2# oil as foaming agent, which is floated in high alkalinity medium. The flotation process is a rough selection, three-stage sweeping, and three-stage selection (returning in the order of the mines). When the ore grade copper is about 3%, the copper grade of concentrate is 17%, the silver is about 50g/t, the recovery of copper is between 85% and 88%, and the recovery rate of silver is <60%.
After on-site examination by the Institute of Minerals Comprehensive Utilization of the Chinese Academy of Geological Sciences, it is considered that the rough selection and the three-sweep selection are short-choice and long-selection, and the rough selection is not enough. The sweeping time is too long, and the amount of concentrate is large. If there are many pesticides and return to rough selection, the coarse selection foam will become sticky and deteriorate the selection. The mineral processing technical indicators should have potential for improvement. Thus, the conduct of the Shilong copper sulfide copper ore mineralogy of the detailed process carried out flotation trials of new agents, and mine oxide ore exploration test, transformation of the existing beneficiation process plant And the new expansion of the concentrator design provides technical basis.
The Shilong copper ore sample has a high copper grade (3.27%) and a fine mineral grain size. The copper minerals are mainly chalcopyrite, porphyrite and chalcopyrite, followed by Lanhui copper mine and malachite. Gangue minerals are calcite, feldspar, quartz, sphene, chlorite, serpentine like. According to the nature of the ore, the use of quicklime as a pH adjuster, water glass and sodium humate as gangue inhibitors, Y-89 as a collector, 2# oil as a foaming agent, flotation in a weak alkaline medium It adopts one rough selection and one sweeping process, and three selected processes can obtain copper concentrate with copper 20.91% and silver 72.9g/t. The recovery rate is 93.88% copper and 78% silver. Compared with the original process, the recovery rate of copper is increased by 4.15%, the recovery rate of silver is increased by 35%, and the cost of ore dressing is reduced by 3.388 yuan/ton of ore. An exploratory test was conducted on an oxidized ore with a copper grade of 2.38%, and a copper concentrate with a copper grade of 11.8% and a recovery rate of 75.32% was obtained.
The new process chemicals in this research result have less harmful gas emissions and less odor. After the tailings water is clarified, the harmful substances in it are lower than the nationally permitted discharge standards. The ore technical and economic evaluation shows that the economic benefits are significant and have good application effects.

A tee is a branched, reinforced outlet fitting that permits flow at 90 to the main flow. The main flow
passes through the run of the tee. The 90 outlet iscalled the branch of the tee. A straingt tee is manufactured with all three outlets, the run as well asthe branchm the same size. A reducing tee is madewith the branch outlet smaller than the run toaccoomodate the design flow rate.
