Lignite wax
Thread Content
Lignite contains wax (known as lignite wax or montan wax), which is used as a raw material for producing shoe polish; the extraction method involves using leaching to obtain the wax from lignite. Before the year 2000, production took place in Shulan, Jilin, and Xundian, Yunnan in our country; at that time the technology was relatively backward, with batch processes being used for extraction. Are there any companies still carrying out production today? It should be a good choice to launch this project in areas where lignite is available.
The amount of shoe polish needed should be sufficient now. For fine chemical products, the production volume should not be too large.
This finished product should be a good project where resources are available
