Among these reserves, manganese carbonate ores account for 56%, manganese oxide ores （including spongy manganese ores） accounts for 25%, and other types of manganese ore occupy 19%. Rich ores with 〉30% manganese content only account for 5% of the total resource amount, and the remaining 95% are poor manganese ores. Since 1983 when China first began to import, the imported manganese ores have increased annually by 25%. In 2001, the annual imported manganese ores reached 1.71 million tons. From 2010, the annual imported manganese ores increased by greater than 45%, reaching up to 12 million tons in 2015. Thus it seemed that the shortage of manganese ore resources will be a longterm phenomenon for China＇s economic development.展开更多

In 2013, China Geological Survey Bureau deployed a project named ＂Experimental Investigation of Integrated Prospecting Technology for Concealed Carbonate-Type Lead-Zinc Deposits in the Region of Sichuan, Yunnan and Guizhou Provinces＂. This project has been implemented by the Chengdu Center of China Geological Survey since 2013, and the project has run for 3 years. The general objective of this project is to establish an effective and adaptable integrated prospecting methodology （including geological, geophysical and geochemical techniques） in search for deep concealed lead-zinc deposits.展开更多
