Great merits have been identified for the continuous production of copper, and different continuous converting (CC) processes are developed and increasingly used for copper making. For the CC process, the equilibria of multiple phases including iron

Ferrous calcium silicate (FCS) slags are reported to have high potential for use in the copper converting process. However, no phase equilibrium study has been carried out under a simulated converting gas atmosphere in the presence of SO2. In this st

To mitigate possible environmental pollutions, the direct to blister (DTB) route is an important process for copper making because a single, SO2-concentrated stream can be produced. In this study, the ferrous-calcium silicate (FCS) slag system for th

The phase equilibria of iron silicate slags in liquid/spinel/white metal/gas system for the copper converting process were studied, for the first time, under controlled P(SO2) 0.4 atm and P(O2) 10−6 atm in the spinel primary phase field. The liquid

Direct to blister (DTB) accounts for a significant process for copper making due to its simplified process chain and the production of a single stable SO2-concentrated off-gas. In this study, the phase equilibria of iron silicate slags in the Cu-Fe-S

The attachment of copper matte by bubbles in slags, during the copper smelting process, plays a key role in the copper loss. This paper aims to provide an in-depth insight into the copper matte entrainment by bubbles in the copper production. The bub

Herein the phase equilibria in the Si–Fe–Ca–O–S–Cu system in equilibrium with matte at controlled P(SO2) of 0.3 and 0.6 atm and fixed matte grade of 72 wt % Cu were experimentally investigated in the spinel primary phase field. The high-tem

Smelting is an important process in copper production to produce matte and slag. The slag, containing about 1–12% Cu, can be further processed to recover the copper contaminated, but recycle of the slag concentrate reduces overall productivity and
