YS/T 441.3-2014Management rules of nonferrous metals balance. Part 3: Zinc 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 3 441.

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

The partial replacement of YS/T 441.3-2001 "balance of non-ferrous metal smelting management practices zinc mineral processing part." This portion of YS/T 441.3-2001 "balance of non-ferrous metal smelting management practices zinc beneficiation section" compared to the main changes are as follows.

--- Zinc, hot-dip zinc alloy ingot casting sampling, sample preparation and analysis of zinc alloy ingots increased by GB/T 26043 and GB/T 26042 requirements method;

--- Terminology and definitions were perfect, the definition of ore beneficiation part of the increase, concentrates, tailings, the ore; and increased smelting section Defined step recovery, metallurgical recoveries, the total recovery rate of smelt;

--- The ore grade, ore grade, grade tailings and other indicators calculated column in "5.4.2 Calculation Method";

--- Smelting part of the metal content and balance calculations were complements, increasing the difference on recovered material in different situations Treatment instructions;

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

--- On the "inventory method" in the "field measurements" for the appropriate changes;

--- Further improve the material beneficiation flow chart;

--- Zinc smelting process and further improve the material flow chart;

--- According to the actual production of the format and content of Appendix A balance sheet metal were perfect for smelting companies can choose to take the table A.2 format, you can also choose to take a table A.3 and Table A.4 format.

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