Beneficiation technology of Yushui copper-lead-zinc ore
Copper Lead Zinc water jade ore Meixian sunflower ridge plurality of metal mining, ore block YUSHUI. Mine hydrothermal transformation superimposed sedimentary deposits, primarily useful minerals chalcopyrite, bornite, galena, sphalerite, pyrite and other gangue minerals as quartz, feldspar, sericite. The average grade of the mine is Cu 4.08%, Pb 1.85%, Zn 3.28%. A simple plant has been built. The mine believes that the lead is high and the lead-copper ratio is difficult to select. Therefore, the test is carried out for lead-high ore. 1. Ore properties The results of multi-element analysis of raw ore are shown in Table 1, and the mineral composition is shown in Table 2. Table 1 Multi-element analysis element Cu Pb Zn S Fe As SiO2 Al2O3 Ca content% 8.67 19.43 2.93 16.18 22.31 0.014 13.65 1.07 0.97 Table 2 Mineral composition mineral Chalcopyrite Galena Sphalerite Copper ore Pyrite Hematite Siderite quartz Sericite content% 24.11 21.94 3.10 1.81 9.02 8.77 8.97 15.84 2.95 Copper in primary copper sulfide accounts for 79.88%, and secondary copper sulfide accounts for 17.18%. Lead sulfide accounts for 90.47% of total lead, and zinc sulfide accounts for 82% of total zinc. Dissemination size: chalcopyrite generally 0.04-0.08mm, and Fang aluminum ore, zinc blende close disseminated, galena typically 0.02-0.08mm, sphalerite generally 0.05-0.2mm 2, sorting process The ore dressing test was conducted in 1986. First, the ore is ground to 200 mesh and 89%, pre-stirred, then added with zinc sulfate and ethyl sulphate for copper and lead mixing and roughing. The coarsely selected coarse concentrate is ground to -0.043mm to 93%, then Na2SO3 and Fe2 are added. (SO4)3 inhibits lead, and then adds copper concentrate to obtain copper concentrate. The product in the tank is lead concentrate. The copper and lead mixed coarsely selected tailings are further added with CuSO4 and xanthate float zinc to obtain zinc concentrate. 3.

Zinc concentrates do not meet the requirements.

Brief Introductions of Reaming Shells
Reaming shell is used to couple the drill bit with the core barrel. It is suitable for use on all conventional and wireline core barrel. This product is mainly designed to ream the hole to the standard diameter. It can keep the stability of the core barrel. When the old bit is replaced by the new one, reaming shell can also provide sufficient clearance for the new bit. It can also help to resist the abrasion of the core barrel. This type of diamond tool is physically longer than the standard type. So for the compensation of the difference in reaming shell length, an appropriate inner tube extension is necessary to be used.
Ranging from broken and abrasive to consolidated and non-abrasive formations, reaming shells are all suitable to use.
Features of Reaming Shells
1) Acts as a stabilizer for drill bit.
2) Be set with natural or synthetic diamond.
Our reaming shells enjoy the best quality and most special design in the industry. With several different types, we try our best to satisfy any of your requirements.
