Description
The product represented by this dataset is gold raw ore, the starting point and most fundamental raw material of the gold industry chain. Its characteristics are low grade and polymetallic association, with gold mainly occurring as fine or ultra-fine disseminations, making the extraction technology complex. Its upstream is the geological gold orebody, and downstream are the beneficiation and smelting processes, with the final product being gold ingot. The system boundary of this dataset is strictly limited to the cradle-to-gate mining stage, covering the entire process from the in-situ blasting and crushing of the orebody, through underground loading, transport, and hoisting, until the ore is conveyed to the raw-ore bin of the surface beneficiation plant. Specifically, it includes the blasting materials, energy (electricity, diesel), support materials, and water directly consumed in the above mining activities, as well as the waste rock, mine water inflow, and waste gas (such as blasting fumes and diesel equipment exhaust) generated. The dataset includes the main raw and auxiliary materials, energy, and waste in the production process; infrastructure such as the manufacturing of production equipment and the construction of plants is not included within the dataset boundary. The data inventory is formed by merging data from multiple sources.
Activity Description
The entire production process includes the gold mining process, and the entire process covers the process of obtaining gold ore from gold mining.
Process Description
Gold raw ore refers to gold-containing ore mined from mines manually or mechanically, which is usually accompanied by impurity metals such as silver, copper, iron, arsenic, zinc, etc. The ore grade is 2.04%. Gold is crystalline at room temperature and belongs to the equiaxed crystal system with a cubic face-centered lattice. However, gold particles with complete crystal forms in the natural state are extremely rare and often appear in irregular granular, agglomerate, flake, network, dendritic, fibrous or sponge-like aggregates. Pure gold is golden in color and may change color when it contains impurities.
