With the rapid development of new energy vehicle industry, the demand for lithium ore is getting bigger. Lithium ore has two forms of sources, one is in the form of brine, which exists in liquid form and is currently the most important and cost-effective form of lithium resources in the world. Another type is hard rock lithium ore that exists in the form of solid rocks.

  The processing flow of lithium ore:

  1. Brine type lithium ore

  Brine type lithium deposits are mainly distributed in Chile, Argentina, and Bolivia in South America, and exist in liquid form in salt lakes or underground brine reservoirs. By drilling wells to extract brine to the surface, and then using solar energy to naturally evaporate and concentrate it in a huge evaporation pool, it is finally sent to the factory for purification and production of lithium carbonate/lithium hydroxide. Finally, the purified lithium carbonate and lithium hydroxide crystals are dried using a lithium ore dryer to achieve battery grade or industrial grade quality standards.

  2. Hard rock lithium ore

  Hard rock lithium deposits are mainly distributed in Australia, Canada, and Africa, and exist in solid rock forms such as spodumene and lithium mica. Firstly, the raw ore is obtained through open-pit or underground mining, and then through a series of processes such as crushing, grinding, flotation, etc., lithium concentrate is obtained. The lithium concentrate after flotation has a high moisture content and needs to be reduced to the qualified line using a lithium ore dryer before being utilized.

  From the processing of lithium ore, it can be seen that regardless of the form of lithium ore, drying is a crucial step in ensuring product quality, meeting transportation and smelting requirements. There are many lithium ore dryer manufacturers in the market with varying equipment quality. How to choose a high-performance lithium ore dryer? Zhengzhou Jiutian is a leading manufacturer of ore drying machines in China. Based on the characteristics of lithium ore, we have developed a new generation of lithium ore drying machines. Our design philosophy is as follows:

  1. Energy saving: Our lithium ore dryer equipment adopts efficient heat exchange design, excellent insulation, intelligent temperature control and waste heat recovery system, which greatly reduces the energy consumption of the drying process for customers. The equipment is compatible with various heat sources such as biomass fuel, natural gas, steam, etc., reducing dependence on traditional high carbon energy and helping customers obtain returns as soon as possible.

  2. Corrosion resistant design: Lithium carbonate and lithium hydroxide have certain corrosiveness, and battery factories have extremely high requirements for the purity, impurity content, and particle size consistency of lithium carbonate/lithium hydroxide. We provide stainless steel dryers with precise temperature control systems to ensure that product purity is not affected.

  3. Automation control: Our equipment is controlled by automated programs, which are easy to operate and significantly reduce labor costs.

  4. In line with environmental protection concepts: It is best to equip the equipment with a good dust removal and exhaust gas treatment system, customized design, and comply with local environmental standards of the customer.

  5. Wide applications: The equipment can process powdered/block shaped materials and filter cake shaped concentrates.
