The lead - zinc ores copper metal complex sulphide ore, is a type of hard mineral stone.
Acrylic tunnels are mostly used in aquariums, which are convenient for watching fish, and make people feel like they are there. Technically, our factory adopts acrylic one-time pouring sheet, cuts the acrylic slab according to the required size, and uses a customized mold to heat-bend the acrylic sheet into the arc panel needed by the acrylic tunnel. Moreover, our factory can apply arc seamless splicing technology at the corner of the acrylic tunnel to connect multiple tunnels into a whole without gluing, which greatly improves the aesthetics of the acrylic tunnel.

Report summary:
According to the rock and mineral identification report, fine-grained and fine-grained inclusions are common among useful minerals. For example, chalcopyrite is mostly encapsulated in sphalerite at a very fine particle size of 0.001-0.02 mm, and more than 80% of the sphalerite contains inclusions, resulting in a float between sphalerite and galena. The difference in sex is reduced; for example, the particle size of each useful mineral is mainly fine-fine particles, and it is difficult to dissociate the monomer under rough grinding conditions. Complex ore properties make it difficult to separate lead-zinc.
Under a period of grinding conditions, zinc concentrate and mixed concentrate can be obtained by using the process of preferentially selecting lead and then selecting zinc. Copper minerals are dispersed in zinc concentrates and mixed concentrates without a separate product.
The process used in the test is a conventional process, and the agent is also a conventional mineral processing agent, which is easy to produce and manage.
The main test indicators are: zinc recovery in zinc concentrate is 65.03%, zinc concentrate grade is 46.07%, zinc recovery in mixed concentrate is 34.00%, zinc grade is 21.27%; lead recovery in mixed concentrate is 92.11%, lead grade is 22.35 %.
Mixing the silver-containing concentrate 450 g / t silver recoveries 71.94%; silver-zinc concentrate containing 150 g / t, the recovery rate 21.17% silver.
