Approximately 2.0–3.0 t of copper slag (CS) containing 35%–45% iron is generated for every ton of copper produced during the pyrometallurgical process from copper concentrate. Therefore, the recovery of iron from CS utilizes a valuable metal and alleviates the environmental stress caused by stockpile.
Approximately 2.0–3.0 t of copper slag (CS) containing 35%–45% iron is generated for every ton of copper produced during the pyrometallurgical process from copper concentrate. …
For the acid leaching method, not only will a large amount of waste acid be generated in the process of dealkalization but also a large amount of iron oxide and other alkaline substances in red mud will consume a large amount of acid, which will lead to an increase in the cost of dealkalization.
The extraction process for the recovery of iron(III) chloride from the waste liquor comprises the steps of (1) chlorination of waste chloride liquor and adjustment of acidity in the …
This fact is demonstrated by washing concentrates from the dry magnetic separation, when the iron content was easily raised from 52 to 58 per cent. This suggested using a combined process of dry magnetic separation …
The Fe content in leaching residue reaches 78.17% by removing 88.96% SiO 2 and further increases to 90.45% by magnetic separation with Fe recovery of 85.20%. Therefore, alkali leaching–magnetic separation is suitable for treating reductively roasted copper slag because of the high Fe content in concentrate and comprehensive recovery of silica.
Separation of iron-binding peptides The enzymatic hydrolysates (about 20 mg of protein) were demineralized by Chelex 100 resin and then were mixed with equal volume of 20 mM of sodium acetate buffer (pH 4.0) and fractionated by ion-exchange chromatography on a SP-Sepharose Fast Flow column (1.6 × 50 cm).
A core-shell structure was formed of iron precipitate and magnetic iron ore seeds, which can be magnetized and coalesced in magnetic field, accelerating the solid-liquid separation.
According to the sieve plate size, the garbage can be divided into two parts: larger than 50mm and smaller than 50mm. After going through the magnetic separation system, the iron materials in the organic materials (smaller than 50mm) can be selected out. Then the organic matters can be used for composting. Plate Feeder Uniform distributing machine
When the metallic iron is transformed to lepidocrocite, it is beneficial to the separation of titanium and iron in the corrosion product due to the significant density difference between …
Because the crystal water in limonitic ores will report to the iron ore concentrate in magnetic separation, the iron ore concentrate grade is limited to about 52% Fe. Figure 9.17 …
For proper waste separation, dispose of the following items in your organic waste, for example: Coffee & Tea Filter; Leftovers (fish, sausage, cheese, bread, etc.) Eggshells; …

The transformation of metallic iron determined the characteristics of Fe-bearing products, such as mineral phase and particle size, which are the key to the Ti–Fe separation in the corrosion products. Therefore, it is essential to study the transformation mechanism of metallic iron and Ti–Fe separation for the corrosion process of reduced ilmenite.
Gas cleaning process sludge, a waste generated from steel plants contains a significant amount of iron and carbon value which can be recovered and reutilize. The present study focused on the magnetic separation of iron values from the gas cleaning process sludge at varying intensity (1000–4000 Gauss) and evaluated the grade and recovery.
Waste separation means that different types of waste are collected and recycled separately. In Germany, waste separation starts with the consumer, i.e. s must sort their waste and put it in separate bins and containers. A large part of the waste generated in Germany is reused and composted, which saves resources and protects the nature.
