Production of lithium by tank leaching process -Lithium - Ion Battery Equipment

U.S. company uses tank leaching process to produce lithium -Lithium - Ion Battery Equipment

GlobalGeoscience, which explores and develops lithium ore in Riolette, Nevada, USA, strives to become the world's first company to produce lithium ore by tank leaching. The first stage of Rhyolite Ridge project is feasible Sexual research has been completed, pointing to low-cost, high-volume production methods for lithium boron.

The company demonstrated different production methods, including tank leaching, heap leaching and agitated tank leaching, and finally chose to conduct tank leaching around the acid plant. Although this process has a large initial investment, the leaching mother liquor has high grade and low production cost in the next step.(Lithium - Ion Battery Equipment)

The main reason for cost saving is the ability to use the steam generated in the production process to generate electricity, and the installed capacity can even reach 20,000 to 30,000 kilowatts. This can reduce the production cost of sulfuric acid for tank leaching to 20-30 US dollars / ton. Another advantage of this process is the low water consumption and small footprint.

Compared to solar evaporation ponds, mechanical evaporators have the advantage of better control of downstream processes, a smaller footprint and less water consumption, thus lower cost.

Dry recycling of tank leach liquor can also reduce investment costs and tailings dam requirements.

Company manager Bernard Rowe said that after weighing the pros and cons recently, a clear development path has been found for the project, and the Riole Ridge project can build a low-cost large-scale lithium-ion project without affecting the environment. Boron mine.

Sulfuric acid is an important factor in reducing the cost of this project. The combination of tank leaching and an in-situ sulfuric acid plant can greatly reduce the cost of sulfuric acid, thus reducing the total production cost.

The sulfuric acid plant can produce a large amount of steam, which can provide thermal energy for tank leaching on the one hand, and the excess steam can also be used for thermal power generation on the other hand. The steam produced by the sulfuric acid plant reduces the costs associated with mechanical evaporation. Tank leaching, coupled with mechanical evaporation, reduces the cost of maintaining stable composition of most concentrated heap leach liquors and simplifies downstream processes.

All pre-feasibility studies will be completed by mid-year, and the company will consider ways to further reduce costs and accelerate payback cycles.
