Comment period open: IRMA draft Mineral Processing Standard

Today the Initiative for Responsible Mining Assurance (IRMA) is pleased to release its draft Standard for Responsible Mineral Processing (Mineral Processing Standard) for a 60-day global public comment period. Download the draft standard (as a Word document or in pdf format).

The draft Mineral Processing Standard is IRMA’s response to stakeholder requests for a global set of best practices that go beyond ensuring responsible practice at the mine site by clarifying expectations at other key points in minerals and metals supply chains.

IRMA’s Mineral Processing Standard will serve as the basis of a global, voluntary system offering independent third-party review and certification of environmental and social performance measures at smelters, refineries and other operations involved in the processing and extraction of minerals and metals from ores, concentrates and scrap materials. It was developed through multi-stakeholder collaboration and the innovation that comes from working across diverse sectors, disciplines, and geographic locations.

The Mineral Processing Standard is incomplete without your valuable feedback. The public comment period begins today and remains open through 16 August 2021.

Next steps

The 60-day public comment period ends 16 August 2021.  Based on the comments and direct feedback from one or more pilot projects, we will revise the Mineral Processing Standard. We aim to release the final Standard in late 2021. We will make the final Mineral Processing Standard available on the IRMA website as well as via the IRMA e-newsletter (sign up here).
