Raw Mineral Separation

Ore composition

During the Permian Period of the Paleozoic Era, approximately 290 million years ago, the indo-china movement was highly active, marking a significant geological period in China's geological history. During this time, three-quarters of China's current landmass completed its assembly and unification. In the region now known as Huade County, Ulanqab, Inner Mongolia Plateau (with coordinates ranging from East Longitude: 113°56'45" to 113°57'23" and North Latitude: 41°52'36" to 41°52'56"), extensive geological changes occurred. The original coarse-grained pegmatitic structure, primarily composed of pegmatite silicate,  was significantly affected by the Late Triassic Yanshan tectonic period (about 250 million years ago), leading to the formation of three distinct translational fault zones. The mineral bodies and magma erupted along these fault zones, and a complex and unique rock foundation gradually formed, covering an overall area of 16.8 square kilometers. The three translational fault structures in different directions created a core enrichment area, infusing various trace elements, including rare earth elements, into the mineralized coarsegrained pegmatitic rocks and magma. This process led to the formation of large phenocrystalline feldspar, tea -colored quartz, and biotite, among other minerals. Under the influence of strong internal stress and geological structural conditions, a secondary mineralization occurred as a result of the subsequent magma intrusion. These transitional intermediate products, enriched with rare earth elements and light metal oxides, underwent further fusion and interaction with the magma, causing the mineral components to fractionate again. During the alternating crystallization of minerals, elements such as the lanthanide series, light metals, selenium, and nutrients required by plants were melted or crystallized into different material forms of the ore body, resulting in the formation of a unique new mineral species known as "wulan crystal".

The complex mineral composition endows the product with new functions.

Over 60 kinds of mineral elements, providing balanced nutrition

Utilizing our independently developed pure physical process technology, beneficial components are enriched, making it a functional new type of fertilizer raw material. The mining process combines dry and wet methods, where the ore is first roughly, medium, and finely crushed, along with wall-breaking and shadow separation. It then undergoes multiple cycles of primary and overflow circulation processes for secondary separation. Different magnetic materials are subjected to two stages of weak and one stage of strong gradient magnetic separation, ultimately leading to vacuum dehydration. The production and processing technology mainly relies on common process equipment for crushing, using coarse and fine crushing equipment, and our self-developed vertical sand-making machines for further fine crushing. High-silica aluminum  grinding machines further reduce the particle size to a minimum crystal grain of the original mineral to 60 mesh for conventional permanent magnetic rough selection separation. Strongly magnetic materials are separated, and then refined through vertical high-gradient electromagnetic ore dressing to achieve high-quality and eco-functional raw materials. This technology effectively ensures that the nutrient elements enriched in the crystalline mica and amorphous substances are not lost, meeting the production requirements for products with different functional needs.

Raw mineral separation process

The company employs the hydrothermal cultivation technology from the Chinese Academy of Agricultural Sciences, which involves processing the parent rock ore of wulan crystal by crushing and grinding it, then adding alkaline soil activators and catalysts. After mixing with water and pouring into molds, the material undergoes a hydrothermal reaction in an autoclave at high temperatures and under saturated steam pressure. The final product, after drying and milling, is ready for market. The wulan crystal raw material, treated with the high-temperature steaming and activation process, has all its mineral elements transformed into a form that can be effectively absorbed and utilized by plants as nutrients. The newly formed mineral particles are refined into nano-scale particles, and the original ore is expanded into a porous, loose structure similar to soil aggregates. The bulk density of the material is reduced, dropping from 0.9-1.0kg per square meter to 0.6-0.7kg per square meter. With a pH of around 11.5, it is a natural mineral material for acid adjustment and nutrient supplementation.

Soil is a complex mixture composed of a variety of different chemical elements, and it is generally believed that there are more than 80 types of elements in the soil. Lanjing Ecological Technology Co., Ltd. primarily uses natural minerals as raw materials, conducts in-depth research on fertilizer formulations, and emulates the nutritional composition of soil with the concept of "from nature, back to nature". By utilizing mineral elements that are already in a stable natural state, it balances and replenishes the gradually depleted elements in the soil. Currently, the annual production capacity of the mineral fertilizer production line has reached 350,000 tons
