Recovery iron from cyanide tailings by anaerobic roasting-persulfate leaching: effect of roasting temperature

Environmental Science and Pollution Research, 2023
Anaerobic roasting combined with the persulfate-leaching process was used to treat cyanide tailings. In this study, the effect of the roasting conditions on the iron leaching rate was investigated by the response surface methodology. Additionally, this study was focusing on the effect of roasting temperature on the physical phase transformation of ...

HIGH‐TEMPERATURE (NTERRUPTED COOKING OF BEEF ROASTS

Journal of Food Science, 1980
ABSTRACT Sensory scores for flavor of top round beef roasts were higher for roasts cooked by a high‐temperature interrupted method than for control samples. For rolled rib roasts, flavor and tenderness of samples cooked by the test method in the electric oven and control samples were similar but control samples were juicier than test ...

Behavior of Arsenic, Antimony and Bismuth at Roasting Temperatures

2015
Arsenic, antimony and bismuth are commonly found in copper concentrates usually as the minerals enargite, stibnite and bismuthinite, respectively. Concentrates having high levels of arsenic and antimony must be pretreated before smelting. Roasting is the preferred method for removing these toxic impurities from concentrates; However, the removal of As,

Research on Intelligent Predictive Control of Roasting Furnace Temperature

2021
A predictive control strategy based on the fuzzy neural network (FNN) for baking furnace is proposed. This method combines T-S fuzzy model with the RBF neural network to form a FNN. The temperature control system of anode baking furnace is taken as the object of simulation and predictive modeling. The T-S fuzzy RBF neural network (T-SFRBFNN) is used to
