Nickel is a chemical element. Chemical symbol, atomic number, atomic weight., belongs to Group VII of the periodic system. The content of nickel ore in the earth's crust is .%. The main minerals of nickel ore are pentlandite [(,)], nickelite [(,)&], gothite or yellow nickel ore, red nickel ore, etc. The manganese nodules on the seabed contain large reserves of nickel and are important prospective resources for nickel.
The mineralogical properties of nickel-copper sulfide deposits around the world are roughly similar, that is, they are mainly composed of pyrrhotite, pentlandite, chalcopyrite, etc. Under epigenetic alteration conditions, they are mainly composed of pyrrhotite, pentlandite, chalcopyrite, etc. It is composed of pyrite, purple sulfur nickel ore, chalcopyrite, etc. Common symbiotic minerals are roughly nickelite, tetragonal pyrite, marcasite, graphite, chalcopyrite and a small amount of platinum group minerals, such as platinum ore and gold and silver ore. Nickel sulfide in the ore, The ratio of copper sulfide and iron sulfide mineral contents, the embedded particle size of sulfide mineral aggregates, the embedded relationship between different sulfide minerals and the types of gangue minerals are the main factors that determine the mineral processing process. In the practice of beneficiation, most precious metals are concentrated in flotation concentrates. Due to the importance of platinum group elements and precious metals in the field of modern science and technology, when formulating certain copper-nickel sulfide ore separation processes, for platinum group elements and precious metals need to be considered in detail.
Most nickel copper sulfide ores have the following properties: 1. The sulfide mineral aggregates are embedded with uneven particle size. , Nickel sulfide minerals are easily pulverized and oxidized, and their natural floatability is similar to iron sulfide minerals. , Some useful minerals are magnetic, such as pyrrhotite, pyrrhotite, chalcopyrite and some copper-containing minerals. , Gangue minerals are easy to muddy and have good natural floatability. Therefore, in the practice of mineral processing based on flotation, coarse grinding, stage grinding, a small number of beneficiation, rapid flotation, and a combined process of desliming, flotation, magnetic separation, and flotation are often used.
The jig, magnetic separator and other mineral processing equipment produced by Henan Bosite Machinery Manufacturing Co., Ltd. are mainly suitable for hematite, limonite, magnetite, siderite, specularite, manganese ore, Lead-zinc ore, galena, tungsten ore, tin ore, placer gold ore, rock gold ore, barite, celestite, fluorite and other metal and non-metal mineral mineral processing, can also be used to process manganese slag, chromium slag , nickel slag, stainless steel slag and other smelting slag, recover useful metals, and the mineral processing effect is very good.
