| Abstract: |
| ROM grade of certain Inner Mongolia Gold Mine is 1.64g/t, and gold is the only valuable metal. The Mine is featured with big reserve, diversified grades and different types of ores. Through analysis on ore properties and mineral processing test results, it was found that the processing and metallurgical indices vary in a great extent. To ensure maximum economic benefit of the Mine, a process to treat high-grade ores with all-slime cyanidation technique and treat low-grade ores with heap leaching technique was adopted. The thesis provided a general illustration on crushing system, all-slime cyanidation system and heap leaching system of the Mine, in addition, under the prerequisite to guarantee design indices and process parameters, the thesis also discussed selection of high-efficient and energy-conserving processing and metallurgical equipment as well as equipment configuration optimization as per site relief. |
