For example, for coal slag that contains 2 ppm (0.0002 %) beryllium by weight, the final action level of beryllium of 0.1 μg/m 3 would be exceeded only when total dust concentrations exceed 50 mg/m 3, a level that is over 3 times higher than the current 29 CFR 1910.1000 (Table Z-1-Limits for Air Contaminants) PEL of 15 mg/m 3 for PNOC ...

Purpose For abandoned slag heaps, the spontaneous establishment of a vegetation cover is usually considered beneficial as it represents a means of phytostabilization. However, for slag containing heavy metals, such a vegetation cover has a potential long-term effect on the fate of the metals. The objective of this study was to …

Ferrous slag is currently underutilized. Although the construction industry does use some slag as an aggregate, most is simply discarded. However, slag could be used to treat acid soils or acid mine drainage. Doing so would both offset the cost of restoring abandoned mine areas, as well as decrease steel manufacturers' current waste …

Abstract Zinc slag (including zinc smelting slag and zinc leach residue) belongs to solid waste from the zinc pyrometallurgical and hydrometallurgical industry. Gener-ated by the pyrometallurgical process, zinc smelting slag contains a high content of zinc, lead, and cobalt as secondary resource. And zinc leach residue, generated in the zinc ...

Plastics are derived from organic products. The materials used in the production of plastics are natural products such as cellulose, coal, natural gas, salt and, of course, crude oil. Crude oil is a complex mixture of thousands of compounds. To become useful, it must be processed. The production of plastic begins with a distillation process …

On the other hand, it can lead to the formation of "Fe," which deteriorates the properties of molten slag and is not conducive to the stratification of slag and matte. 26 Therefore, 6% reducing agent is selected as the optimal condition, under which the recovery of Zn is 83.08%, and the content of zinc in cleaned slag is 1.25%.

Lead and lead–zinc slags are black to red in color and have glassy, sharp, and angular (cubical) particles. The unit weight of granulated lead and lead–zinc slags can vary from less than 2500 kg/m 3 (156 lb cf) to as high as 3600 kg/m 3 (225lb cf). Granulated lead slag is a black granular material having a high specific gravity of 2.65 to 3.79, due to the high …

Zinc slag was used as a natural adsorbent for arsenic adsorption experiments to explore the ability of zinc slag to bind arsenic at room temperature. Briefly, 1 L of wastewater with an arsenic concentration of 2000 mg/L and 50 mL of H 2O 2 were mixed in a beaker, stirred for 1 h, and taken out for later use. H 2O 2 was added to oxidize As(III ...

metals lead, zinc, and silver. Consequently, a refining waste slag is generated during the refining of the crude bismuth by chlorine (Xiong and Xiao, 2005). This slag is unacceptable to lead smelters because the lead in the slag mainly exists in the form of lead chloride, which is volatile at temperature of lead smelting and thus refractory.

Steelmaking plants continuously strive to reduce the environmental load in the steelmaking process, resulting in the recycling of energy, water, and other byproducts. In this chapter, techniques for the treatment and recycling of metallurgical slags are described. Metallurgical slags are considered secondary raw materials and are used or …

China is the leading producer of non-ferrous metals, contributing 47% and 35% of global lead and zinc production, respectively.
