Demonstration of industrial indicators of Chating copper deposit in Anhui Province

Demonstration of industrial indicators of Chating copper deposit in Anhui Province

Chating copper deposit in Anhui Province is a concealed large porphyry copper-gold deposit. The natural type of ore is veinlet disseminated gold-bearing copper ore, and the industrial type of ore is primary sulfide gold-bearing copper ore. The general survey of the mining area lasted from 2009 to 2018, with a cumulative drilling footage of more than 46,100 meters. In order to determine a reasonable industrial index and provide a target area for detailed investigation, the company carried out the demonstration of industrial index of copper deposit in Chating mining area. According to the mineral resources and external construction conditions of the mining area, the mining scheme and beneficiation scheme are demonstrated, and the technical and economic analysis and evaluation are carried out. The recommended industrial indexes are in line with the actual situation of the mining area, which provides a basis for delineating copper polymetallic ore bodies and estimating resources in the mining area. The project won the third prize of excellent engineering consulting.

The project won the third prize of excellent engineering consulting.

Geological prospecting research of Zara gold mine in Eritrea

Geological prospecting research of Zara gold mine in Eritrea

Zara gold deposit in Eritrea is a part of Zara-Bisha metallogenic belt, one of the two main metallogenic belts in Eritrea. On the basis of judging the previous geological data, the company has carried out remote sensing geochemical interpretation, field investigation and anomaly verification, anatomy of typical ore deposits, etc., summarized the mineralization characteristics, ore-controlling factors and genesis of gold deposits in the mining area, and delineated a number of target areas with prospecting value.

Infrastructure exploration of Guinean Boffa bauxite mine

Infrastructure exploration of Guinean Boffa bauxite mine

The design scale of Guinean Boffa bauxite mine is 12 million tons/year. Under various harsh conditions such as rampant overseas epidemic and local election turmoil, the project team of the company strictly guards against death and organizes scientifically. The accumulated drilling footage is more than 30,000 meters, and the amount of bauxite ore transported abroad is about 52 million tons, which provides reliable resource reserves for the sustainable development of the mine. The project adopts spiral waterless drilling technology, which significantly improves the exploration efficiency on the premise of ensuring the drilling quality. At the same time, the three-dimensional geological model of the deposit is established by using three-dimensional software, which greatly facilitates the production management and stope ore matching of the construction unit, and shows the rich overseas construction experience and first-class laterite bauxite exploration technology level of the company.

Bauxite exploration in Xiaolongmiao mining area, Mianchi County, Henan Province

Bauxite exploration in Xiaolongmiao mining area, Mianchi County, Henan Province

Bauxite exploration in Xiaolongmiao mining area, Mianchi County, Henan Province is one of the large-scale bauxite exploration projects completed by our company. The lithology of strata in mining area is complex, and there are many mined-out areas. In the process of exploration and construction, the company took the lead in adopting hydraulic thin-walled drilling tool rope coring technology in China, which has small construction area, convenient relocation and high core recovery rate. Combined with drilling work, transient electromagnetic method (TEM) is used to comprehensively explore mined-out areas, which can intuitively and accurately reflect the distribution of underground mined-out areas and provide more accurate guidance for future mining work. This project won the third prize of non-ferrous metal geological prospecting achievements of China Nonferrous Metals Industry Association in 2020.

EPC-based Anode Slime Pre-processing Project for Technical Upgrading of Gold and Copper Comprehensive Recovery Operation under Hunan Shui Kouhan Nonferrous Metals Group Co.,Ltd.

EPC-based Anode Slime Pre-processing Project for Technical Upgrading of Gold and Copper Comprehensive Recovery Operation under Hunan Shui Kouhan Nonferrous Metals Group Co.,Ltd.

The project construction was started in June 2016 and was completed in 2017. It has an important demonstration and benchmarking effect on the comprehensive design and implementation of copper smelting projects. Innovation and optimization of process design: The integrate process of hydrometallurgy and pyrometallurgy is applied to process high-value anode slime rich in precious metals such as gold and silver with the capacity of 800t/a. The anode slime is filtered by a filter press. The filter residue is naturally oxidized before 2- stage concentrated sulfuric acid slurring and then sent to calcinations operation. The selenium dioxide in the off-gas is reduced by sulfur dioxide to produce crude selenium. The calcine is hot dipped . And active copper powder and copper wire is used for replacing silver in leachate. The products include crude selenium powder, crude silver powder, pretreatment slag and valuable metals such as gold, silver and selenium are effectively recovered.

Coal, electricity and aluminum integration project of Wachangping bauxite mine for State Power Investment Corporation Limited, Zunyi, Guizhou.

Coal, electricity and aluminum integration project of Wachangping bauxite mine for State Power Investment Corporation Limited, Zunyi, Guizhou.

The project is the first metal mine to adopt the longwall comprehensive mechanized mining technology. It has formed a production capacity of 3,000 t/d bauxite by “one shaft，one face and one set” of integrated mining equipment. It successfully solved problems and technological difficulties of roof corrosion development, water filling, safety, high-efficiency and low dilution loss of unstable and gentle-inclined thin-medium thick difficult-mining orebody, which adds a new mining technique for metal mining.
