Conducts a survey with the aim of acquiring interests in mineralresources

JOGMEC conducts a joint survey for resource development in cooperation with exploration bodies such as state-owned mining companies of resource-producing nations, and foreign companies. Before initiating a survey, JOGMEC signs with counterparties of the joint survey a Joint Venture Agreement (JVA) that contains a provision on transfer of projects to Japanese companies. JOGMEC then transfers survey results to Japanese companies, and assists them in continuing their exploration and development of the projects.

Equity capital and Loan

To ensure a stable supply of mineral resources, it is important that Japanese companies participate in mining projects. However, investment in the upstream sector of mineral resources is not only associated with the great risk of failure, but in many cases a large amount of funds are required.JOGMEC assists Japanese companies to carry on businesses in the upstream sector of mineral resources through financial support. One of our financial support schemes is providing funds required for mineral resources exploration projects in the form of equity capital or loan, and also providing equity capital for mining asset acquisition.

Promotion of exploration technology development for current needs

JOGMEC is conducting technological development of mineral exploration using remote sensing and high resolution geophysics.These are R&D to detect accurate information from the earth observation data effectively and efficiently and to utilize geophysical data etc., for integrated analysis technology.

Exploration Technology Development for Mineral Resources

Project overview

It has successfully detected distributions of hydrothermal alteration minerals related to mineralization by optical sensor data for ground reflection of the sun light through the technology development on detection of hydrothermal alteration zones. Moreover, geological classification and detection of host rock of ore deposits have been available by analyses on TIR data DEM data and SAR data. These techniques are being utilized for mineral exploration to delineate promising areas from a wide region.

Exploration Technology Development by Remote SensingMajor achievements

Electro and Electromagnetic methods including TEM (Transient Electromagnetic) method have been applied because the alteration zone around metallic mineral deposit has conductive characteristics (low resistivity) in comparison with normal rocks. Exploration depth and accuracy of TEM method have been improved by using SQUID (High Temperature Superconducting Quantum Interference Device) which is a very sensitive magnetic sensor, in comparison with conventional TEM equipment the capacity of which is insufficient for deep seated ore deposits. JOGMEC has successfully developed a TEM method equipment (SQUITEM) using SQUID. Then, improved SQUITEM No.3 is being utilized for mineral resources exploration of JOGMEC’s projects.

Metal Technology Center JOGMEC/MMIJ Symposium2017

Promotes development of production technologies looking ahead to the future

JOGMEC has promoted technological development needed to extract metals from mineral ores, and enrich and use them as resources.With the recent decline in ore grade and the increase in impurity content, technologies for efficient metal extraction from mineral ores have become increasingly important. Due to this trend, JOGMEC is developing technology for hydrometallurgical extraction of copper out of low grade ores, and mineral processing for complex sulfide ores at the Metals Technology Center located in Kosaka town, Akita prefecture.In addition, at the Metals Technology Center, in order to be a research base for production technology in Japan, JOGMEC will expand analyzers and facilities such as MLA, advance Open-Laboratory, promote joint research with research institutions and companies, analysis support, etc.

Development of production technologies

JOGMEC conducted collaborative research with laboratories for collecting fundamental data about solvent extraction.

Research and study for developing technology for extracting rare earths from refractory ores (from 1994 to 1997)

JOGMEC developed technology for extracting gold from pyrite concentrate by bioleaching

Collaborative research for effective use of unused metallic resources(from 1990 to 1994)

JOGMEC developed technology for detoxifying flue dust generated in copper smelters containing high levels of

arsenic and around 10% of valuable metals such as copper, and for extracting valuable metals from the flue dust.

Joint development of technologies for detoxifying and extracting metals flue dust from smelters (from 2001 to 2006)

Aiming to reduce power consumption in copper production by introducing electrorefining, in which power

consumption is less than electrowinning which is generally used for copper production from recycling material.

Technical Development on electrorefining process of low grade copper anode to reduce power consumption (from 2013 to 2016)

Technical Support

Technical support to meet the needs of the operation sites

With the progress of resource development, the target of resources development by Japanese corporations is forced to shift toward mining which brings about higher technical risks. Currently, the technical ability for mineral processing, metal, refining, and so on, is critical to the competitive strength of corporations. In the midst of this situation, JOGMEC supports technology improvement projects at the operation sites where Japanese corporations are involved, and also evaluation of mines and F/S of mine development projects. This support takes the form of a joint study program between Japanese corporations and JOGMEC. It aims to upgrade competitive strength of Japanese corporations to acquire mining interests, and also contribute to the stable supply of resources to Japan in the future.
