Comprehensive Utilization and Sustainable Development of Bauxite in Northern Guizhou on a Background of Carbon Neutralization

Abstract

As a developing country, China is also a major producer and consumer of mineral resources. At present, China is still in a critical period of rapid development of industrialization and urbanization, which will inevitably lead to huge resource consumption. It is only 30 years between the peak carbon consumption and the timepoint planned to achieve the goal of carbon neutrality. Coming from a background of dual pressure in terms of the total amount and intensity of “carbon neutrality”, the development and utilization of mineral resources has become one of the important factors in affecting and realizing carbon neutrality in China, and comprehensive utilization has become increasingly important. There are abundant bauxite resources in northern Guizhou, more than 700 million tons, and an industrial resource chain could be built around bauxite. The ore-forming process of bauxite is very complex, and there are enrichment phenomena of other useful elements in the ore-bearing rock series, among which the enrichment of associated Ga, Li and rare earth elements is very obvious. It is of great economic and scientific significance to study the migration law of associated Ga, Li and rare earth elements and to find out whether these elements in bauxite have development value. On the basis of systematically collecting and sorting previous research results, this study carried out supplementary tests on some areas with insufficient data; summarized and studied the migration law of associated Ga, Li and rare earth elements in the Wuzhengdao bauxite deposit in northern Guizhou; and conducted a feasibility analysis on the development and utilization prospects of associated Ga, Li and rare earth elements.

A Habitable Earth and Carbon Neutrality: Mission and Challenges Facing Resources and the Environment in China—An Overview

“…To ensure the health and safety of underground workers and safe production, the ventilation rate must meet the relevant requirements, resulting in a huge amount of gas being directly discharged into the air. However, under the existing technical conditions, effectively using such low-concentration ventilation gas is difficult (Figure 4) [22][23][24][25][26][27][28].…”

Thoughts on Teaching Reform of Resources Majors in Colleges and Universities under the Background of Carbon Peak and Carbon Neutralization—Taking Mineral Resources Exploration Course as an Example

“…Considering the close relationship between carbon capture, carbon flooding, carbon sequestration, carbon conversion and other carbon removal measures and oil and gas development, the development of these measures can not only realize the goal of carbon sequestration but can also greatly improve the levels of oil and gas production. China's high dependence on foreign oil is a highly significance problem [20][21][22][23]. (2) To promote the rapid development of key technologies in the industry, it helps to take into account the new international situation and industry development.…”
