Thickener is an important solid-liquid separation equipment in modern ore dressing plants. It is widely used in tailings thickening, concentrate dehydration and water recycling processes. The high dehydration efficiency of thickener can recycle and utilize the resources, and at the same time improve the production efficiency of the ore dressing plant, so as to control production costs and protect the environment. The following will introduce the working principle of thickener and the application of different types of thickener in ore dressing plants, so as to help you choose the appropriate thickener equipment according to your needs.
Quartz ore is an important non-metallic mineral. It is primarily composed of silicon dioxide (SiO₂). High-purity quartz is a key raw material in industries like glass, ceramics, photovoltaics, and semiconductors and so on. Natural quartz ore often contains impurities such as iron, aluminum, mica, and feldspar, these impurities affect quality and usability of quartz sand. Mineral processing is essential technology to purify quartz ore. The selection and efficiency of quartz sand mineral processing equipment directly impact purification results and product costs. This article will introduce the types and selection of quartz ore processing equipment.
Gold leaching is an important part of gold smelting, among which CIP (carbon-in-pulp), CIL (carbon-in-leach) and heap leaching are the three most widely used processes. They are suitable for different types of gold ores and have different economic and environmental impacts. This article will analyze these three gold leaching methods in detail and explore their process optimization and development trends.
Copper is one of the most widely used metals in the world. It is widely used in fields such as electrical and industrial machinery. The extraction of copper is a complex process involving multiple stages from mining to refining. Among them, the flotation process plays an important role in the extraction of copper metal from copper ore. Flotation is widely used in the treatment of various ores. It mainly relies on the difference in the properties of the mineral surface to selectively recover valuable copper-containing minerals while removing gangue minerals. This article will introduce the flotation process of different copper ores to help you understand the flotation process of copper ores.
Lead-zinc ore is an important non-ferrous metal resource with a wide range of uses. At present, most of the lead and zinc are obtained through the separation of lead-zinc sulfide ore. However, with the development and utilization of resources, the easy-to-sort lead-zinc sulfide resources are gradually depleted, and the mining of lead-zinc oxide ore has gradually been paid more attention.
The iron ore tailings in China have characteristics such as low grade, small particle size, fine grain size of iron-containing mineral intercalation, complex symbiosis, easy to slime, etc. It causes difficulties to iron tailings re-processing. Under the condition of increasing shortage of iron resources and increasing dependence on foreign countries, it is especially important in strengthening iron tailings re-processing.
China's potassium feldspar rich resources are few, and often coexist with other impurity minerals, especially a small number of impurities such as iron and titanium, which affect its quality and application, so it needs impurity removal. At present, the main impurity removal methods of potassium feldspar are magnetic separation, flotation separation, acid leaching process and combined process. Specifically, the appropriate impurity removal process should be selected according to the occurrence state of impurity minerals and the embedded particle size.
The belt conveyor is a kind of material transportation equipment commonly used in the current concentrator, in which the belt plays an important role as the load bearing and transport device. In the ore dressing process, the belt deviation is one of the common problems of belt conveyor, that is, in the operation, the center line of the belt deviates from the center line of the belt conveyor, so as to turn to one side.
Quartz sand, also known as silica sand (quartz sand with SiO2 content above 98.5%, silica sand with SiO2 content below 98.5%), can be made into high-purity quartz sand after the mineral processing and purification. It is widely used in glass, ceramics, metallurgy, casting and refractory industries.
On January 18th, Xinhai Mining EPC organized the 2020 Safety Summary Meeting and 2021 Safety Production Kick-off Meeting. Mr. Zhang Yunlong, chairman of Xinhai Mining, Mr. Han Qingwang, director of administration and operation, and the heads of various departments of the Production Management Center attended this meeting. This meeting was presided over by Wang Chuanmo, director of the safety and environment section of Xinhai Mining. In the meeting, Director Wang Chuanmo led all departments to clarify the principles of safety production purposes, summarize the lessons learned in the safety production in 2020, implement the responsibility of safety production in each department, build up the safety production defense line, and make sufficient preparation for the safety production at the beginning of 2021.
