Abstract. The suitability of Glass Ionomer Cements (GICs) for use in orthopaedics is retarded by the presence in the glass phase of aluminium, a neurotoxin. Unfortunately, the aluminium ion plays an integral role in the setting process of a GIC and its absence is likely to hinder cement formation. However, zinc oxide, a bacteriocide, can act ...
Zinc processing - Ores, Refining, Alloying: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world's output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a …

The application of oxygen-rich side blowing furnaces in the direct lead-smelting process has excellent potential and ideal capability for co-processing various feedstocks, such as zinc leaching residues, jamesonite precipitates, lead paste and lead–silver dregs, etc. In this study, the industrial application for this process has been …
Iodide ions significantly alter the intermediate reaction steps, leading to a kinetically favorable mechanism through coordination with Bi 3+ to continuously refresh and activate the interface. The resulting secondary neutral Zn||Bi 2 O 3 battery delivers a high specific capacity (1960 mAh cm –3 ), exceptional rate performance, and remarkable ...
3.1. Leaching and precipitation of zinc . As the zinc in the bismuth refining slag existed mainly as zinc chloride, which was readily soluble in water, a water leaching was chosen to treat the slag first. 100 g ground slag (<0.15 mm) was leached at a liquid/solid ratio of 4:1 and a temperature of 25 °C for 2 h. The leaching liquor contained 4. ...
Non-sulfide zinc ores are an important resource that can be used for the production of zinc. These ores were the prime source of zinc metal production for hundreds of years, but their significance decreased during the early 20th century due to the development of flotation and smelting techniques for zinc sulfides (Schneider et al., 2008).
The roasting temperature is critical for enhancing product quality, reducing air pollution, and ensuring the long term operation of the zinc roasting process. However, optimizing the roasting temperature is challenging due to complex reaction mechanisms, feed composition fluctuations, and the coupling relationship with downstream processes. …
Most bismuth is found in nature in the form of associated element in lead‑zinc ore, copper ore and other minerals (Reyes-Aguilera et al., 2008). Consequently, it is usually obtained as a by-product in metallurgical processes of other metals. ... According to this process, bismuth was dissolved in H 2 SO 4 –NaCl solution with leaching ...
