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 1 441.
This section drafted in accordance with GB/T 1.1-2009 given rules.
The partial replacement of YS/T 441.1-2001 "non-ferrous metal smelting part of the norm copper beneficiation." This portion of YS/T 441.1-
Compared to 2001, the main changes are as follows.
--- Updated the reference standard;
--- Metal balance management responsibility has been revised to delete part of the duties and powers;
--- Define some of the new ore beneficiation, ore, tailings, middlings, metal balance terms, partial deletion of the whole smelting smelting plant recovery
Rate, the new definition of the recovery process, the total recovery of smelting, metal balance of terms;
--- Further improve the material flow chart beneficiation and smelting process;
--- According to the actual situation on the balance sheet metal format has been improved.
The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized.
