Services & Products

As a supplier of nonferrous materials covering areas of operations from raw materials procurement to smelting/processing outsourcing and product marketing of nonferrous metals including copper as the main material, PPC aims to obtain the satisfaction and trust of our customers and of society as a whole, and to become a respected multinational corporation that helps create a sustainable society.

Raw Materials Procurement

Stable procurement of high-quality raw materials

PPC is among the leading buyers, procuring approximately 1.8 million tons of high-quality copper concentrates annually from around the world. PPC's main sources of copper concentrate are the Caserones Mine (invested by JX Nippon Mining & Metals and Mitsui Mining & Smelting), the Los Pelambres Mine, the Escondida Mine (invested by JX) and the Collahuasi Mine (invested by Mitsui). These mines help ensure that PPC meets its long-term raw material requirements.
Also PPC is enhancing efficient use of nonferrous resources by promoting the utilization of recycled materials. Through such effort, PPC will contribute to the sustainable development of society.

Caserones Mine (Chile)

Caserones Mine

The Caserones Mine is a resources development project wholly owned by Japanese companies. Production of refined copper began in March 2013 and of copper concentrates in May 2014. Copper concentrates to be produced here is expected to contribute to the stable supply of copper resources to Japan through the year 2040. The development of the project is also important for the growth of the Chilean economy, and each of the companies investing in it will provide support toward stable operation, helping to strengthen ties between Japan and Chile.

Smelting & Processing outsourcing

Refined Copper ~Production of high-quality copper~

PPC outsources smelting & refining operation to JX Metals Smelting Co., Ltd. (100% subsidiary of JX Nippon Mining & Metals) Saganoseki Smelter & Refinery and Hitachi Works, and Hibi Smelting Co., Ltd. (100% subsidiary of Mitsui Mining & Smelting). Hibi Smelting re-outsources to Hibi Kyodo Smelting Co., Ltd. Tamano Smelter.
Each of these sites has high technical capabilities, cost-competitiveness, and productivity. At the same time they are meeting rigorous environmental standards in Japan. Aggregate production capacity of refined copper totals 650,000 tons per year (450,000 tons from Saganoseki and Hitachi, and 200,000 tons from Tamano※), the largest output in Japan and among the largest in the world. Also produced refined copper has earned a solid market reputation for quality.
※PPC's outsourcing quantity out of total capability 290,000 tons

Marketing focused on the advantages of each product

Carefully responding to various requests of customers, PPC supplies high-quality precious and rare metals. Gold ingots from the Saganoseki Smelter & Refinery of JX Metals Smelting receive an assurance report from an auditor in accordance the Third-Party Audit Guidance set forth by the London Bullion Market Association.
Taking advantage of its nationwide production and transportation network, PPC efficiently supplies around 2 million tons of sulfuric acid per year, which include by-products from the zinc smelting process of Mitsui Mining & Smelting.


Operation of Combo-Vessels between Japan and Chile for efficient logistics

PPC exports sulfuric acid to Chile for use of production of refined copper by SX-EW process while imports copper concentrates from Chilean mines. For efficient logistics, PPC began operation of MV "MAR CAMINO" in September 2010 which was the only Combo-vessel in the world at that time to transport both sulfuric acid and copper concentrates. In December 2013, PPC started operation of the sister vessel MV "KORYU". These 2 Combo-vessels enable PPC to transport in total around 400,000 tons of copper concentrates and 240,000 tons of sulfuric acid per year.

Social Responsibility for Quality and the Environment

PPC's basic environmental policy is contributing to the preservation of the global environment by helping improve the productivity of resources and materials.
PPC's smelting & processing contractors maintain systems for quality management and environmental management at their production sites by obtaining external accreditation under ISO 9001 and ISO 14001.
