YS/T 441.4-2014Management rules of nonferrous metals balance. Part 4: Tin enrichment and metallurgy (English PDF)

Foreword

YS/T 441-2014 "non-ferrous metal balance management practices" is divided into five sections.

--- Part 1. Copper smelting mineral processing;

--- Part 2. lead smelting mineral processing;

--- Part 3. zinc smelting mineral processing;

--- Part 4. tin smelting mineral processing;

--- Part 5. gold, silver smelting.

This section is YS/T Part 4 441.

This section drafted in accordance with GB/T 1.1-2009 given rules.

The partial replacement of YS/T 441.4-2001 "balance of non-ferrous metal smelting section Practices tin beneficiation", and this part of YS/T 441.4-2001 Compared to the main changes are as follows.

Mineral Processing Section --- term increase of "ore", "concentrate", "tailings" and the "mine," "yield", "recovery" and the definition of smelting section Added "metal recovery", "smelting recovery" and other definitions;

--- Of "stewardship" relevant content has been simplified;

--- Further improve the "flow chart dressing materials" and "smelting materials flowchart" made some modifications;

--- According to the actual production of the format and content of Appendix A balance sheet metal were perfect.

The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized.
