“…Hence, heavy metals uptake increased with the increment of heavy metal by the used plant. The use of 5mM EDTA upgrades the uptake of heavy metal [40][41][42]. It has been reported that EDTA enhances the availability of heavy metal to plants and thus increases the accumulation in their shoots [43][44][45].…”

In these last decades, excessive metal concentration pose serious contamination in soils. Therefore, it is urgent to develop and adopt a new strategy and technology to remove soil contaminants. Here, the phytoextraction was considered as a recently developed approach to clean up metal-polluted soils in that the plants are used to translocate the toxic metals from the contaminated soils. Therefore, this mini-review provides a perfection of recent knowledge related to the heavy metal phytoextraction from soils and their accumulation in plants. It has been reported that EDTA enhances the availability of heavy metal to plants and thus increases the accumulation in their shoots. In addition, fundamental and basic advancement has been made on the molecular aspects and the physiological regarding tolerance and metals phytoaccumulation in plants. A multidisciplinary strategy is warranted to make phytoextraction a plausible trade technology to remediate metal-polluted soils. Hence, the purpose is to integrate soil-related and biological progress to suggest research needs and future direction.

“…The lter cake has a high Cadmium concentration and cannot be neglected as a secondary resource of Cadmium reclamation) Gharabaghi,et al A. 2022;Roshanfar, et al 2020;Safarzadeh et al 2007). The main challenge in Cd recovery is nickel separation from Cadmium (Gharabaghi, et al 2012;Safarzadeh, et al 2010;Safarzadeh et al 2008).…”

During the hydrometallurgical production of Zinc, filter cake obtained from the purification process of Zinc sulfate solution can be considered one of the essential secondary resources of Cadmium. In the current research, using the Taguchi method, the effects of various parameters such as dissolution reaction time (10–40 min), temperature (25–80°C), sulfuric acid concentration (2–11 vol.%) and particle size distribution (four size fractions) under liquid/solid ratio of 10 and stirring speed of 600 rpm on leaching of Cd dissolution from Cd-Ni filter cake were evaluated and optimized. The experimental plan was designed using an orthogonal array, L16 (44), which denotes four parameters with four levels. The optimum dissolution conditions proposed by the Design Expert software were a reaction time of 40 min, temperature of 80°C, sulfuric acid concentration of 8 vol. %, and particle size distribution of -75 + 53 µm with predicted dissolution content of Cd equals to 93.15% by the software. In the optimum condition, 95.2% of the Cd content was leached during the verifying test. According to the results, reaction time, particle size distribution, acid concentration, and temperature are the most affecting parameters on Cd dissolution, respectively. Separation of Ni and Cd present in the solution after dissolution using sodium sulfate precipitation in the pH range of 1 to 5 was studied, and the results show that at pH = 3, maximum separation of Ni and Cd (with weight ratio of Cd to Ni in the precipitates equals to 46.2) was achieved.

“…Metallic zinc as an important member of the nonferrous metals is produced from the secondary zinc resource, its sulfide ores, oxide ores and silicate ores using pyro-and/or hydrometallurgical processes [1][2][3][4]. The modern extractive metallurgy of zinc is dominated by the roasting-leaching-Zn electrowinning process [2,3]. As the main zinc resources (like high grade ZnS ores) deplete rapidly, and the metallic zinc demand increases quickly, the siliceous types of zinc resources as an alternate resource are becoming more attractive [4,5].…”

The technical practicability of high temperature leaching process using willemite concentrate as the materials was developed in the study for extracting base metals. The factors affecting the leaching rates of zinc, iron, and silica from willemite concentrate were investigated, and optimized for maximum zinc extraction and minimum iron and silica dissolution to meet the needs of solution purification. Under the studied conditions (413 K, 0.81 mol/L sulfuric acid, duration 60 min, liquid to solid ratio (L/S) 10 mL/g, agitation speed 550 rpm, particle size of −250 + 300 mesh and 1.4 MPa pressure), up to 97% zinc was leached into lixivium together with approximate 5.72% SiO2 and 21.11% Fe. The performance of liquid-solid separation was also improved with decreasing silica dissolution under the experimental conditions used.
