Chloride Removal from Industrial Soils and Zinc Slag in

Jan 01 2019 The present study attempts to investigate the chloride removal from industrial soils and zinc slag in zinc production companies. The presence of chloride in factorys samples causes some problems such as the anode erosion in electrolysis cells negative effects on the quality of zinc sheets and reducing the quality of product. Having said that decreasing the amount of chloride ion will .

Utilization of LinzDonawitz slag from steel industry for

Jan 27 2020 The LinzDonawitz LD slag is an industrial waste generated in LinzDonawitz process of steel making. It is not gaining importance in construction industry because of its volume instability and presence of excessive phosphorous and sulphur content. Suitable accelerated ageing and masking of harmful materials can improve the engineering properties of LD slag.

Removal of Copper from the Sulphide Copper Smelting Waste Slag

The applicability of chloridizing roasting for removal of copper from the sulphide copper smelting waste slag of the Karabashmed copper-smelting plant is investigated. Calcium chloride CaCl2 was used as chlorination agent. It is established that the chlorinating roasting of the initial slag presented by fayalite 2FeOSiO2 hasnt led to noticeable removal of copper.

Development of a process for producing highpurity calcium

A new type of process for producing highpurity calcium carbonate from waste cement powder was developed. The process consists of two main reactions extraction of calcium in the form of calcium ions from waste cement powder in a water slurry by pressurized CO 2 typically at several MPa and precipitation of calcium carbonate CaCO 3 from the extracted solution by reduction of the CO 2 .

Steel Converter Slag as a Raw Material for Precipitation

In this work we study the possibility of utilizing steel converter slag a byproduct of steel manufacturing for production of pure calcium carbonate. The dissolution of calcium from steel converter slag by using acetic acid as a solvent and the precipitation of pure calcium carbonate from the resulting solution were experimentally investigated. It was found that while strong solutions of .

Frontiers Performance of Separation Processes for

In this work experiments were performed to determine the filterability of calcium carbonate produced with an alternative calcium carbonate production concept. The concept uses steelmaking slag as raw material and has potential to fix CO2 emissions and utilize steelmaking slag simultaneously. As calcium carbonate is precipitated in a solution containing ammonium chloride calcium chloride .

Waste and Recycled Materials in Concrete Technology

Jan 01 1983 Waste and Recycled Materials 661 .3.1 Furnace clinker A substantial amount of unburnt coal and other impurities is contained in furnace clinker. It is used mainly in the manufacture of concrete blocks. Because furnace clinker contains sulphates and chlorides it is not recommended for producing reinforced concrete.

Synthesis and characterization of calcium carbonate

Apr 21 2020 Yellow phosphorus slag is a kind of solid waste produced during the production of yellow phosphorus by the dry process. About 810 tons of waste residues may be produced during the production of 1 ton of yellow phosphorus. The main chemical composition of yellow phosphorus slag is amorphous calcium silicate. Hence the amount of calcium is .

Development of a Novel Titania Slag Upgrading Process

Nov 20 2015 This process offers the following advantages as compared to the current hydrometallurgical processes i treatment of acid waste solution is not necessary owing to no use of acid ii the recovery of chlorine is possible by oxidation of chloride wastes because the iron in the slag is chlorinated in a dry form iii high-grade TiO 2 feed can .

Ilmenite for pigment and metal production OAText

The sulfuric acid treatment process of the slag however still suffered from the disposal problem of the waste acid and as a result it was abandoned in the 1980s and replaced by a new technology based on upgrading the slag to 94.5 TiO2 by leaching away most of the impurities by HCl under pressure to render it suitable for chlorination.
