“…This claim is based on the pH determination analysis according to this analysis a 1 gr of powder of sample was dissolved in 50 ml of distilled water [14] and placed in a shaker incubator was observed pH of solution was fixed in the range of 7. this analysis proved powder neutrality. Finally the pH increases until the third day and then pH decreases because of the ferric ion hydrolysis and protons released (Eq.2-4) [15].…”

Abstract:The toxicity of heavy metals has important role in thermophilic microorganism growth in bioleaching of e-waste. The mobile phone touch screen has high concentration of several heavy metals that caused negative effect on bacterial activity and metals recovery. In the present investigation, Acidithiobacillus ferrooxidans was adapted to powder of mobile phone touch screen. The serial subculturing approach was used for bacterial adaptation with heavy metals. The experiments began with 0.1 wt/vol.% pulp density eventually increase to 2.5 wt/vol.%. All experiment conducted in 100 ml 9k medium at the initial pH 2 and 2% (v/v) inoculums. The effective parameters such as pH, Eh, Fe 3+ , cell concentration were studied and the results confirmed as well as each other. Indium recovery for adapted cell, non-adapted cell and control were 100% (adapted) , 10% (non-adapted) , 1% (control) , respectively. Finally, it is essential that the bacteria become adapted with the heavy metals and consequently an acceptable bioleaching process will be achieved.

“…The view was supported by another study of Bajestani et al (2014) [12],who used the Box-Behnken design of response surface methodology to study the bioleaching of metals from spent Ni-Cd battery. Effects of particle size, initial pH, and initial Fe 3+ concentration on the recovery efficiency of nickel, cadmium, and cobalt were studied.…”

“…The authors confirmed these results using an experiment at optimum condition, which resulted in 87%, 67%, and 93.7% recovery of Ni, Cd, and Co, respectively. [12] All these studies used Acidithiobacilli bacteria. Fungal recovery of metals from battery waste has not been tried in recent past due to the long processing time, the requirement of constant nutrients supply for their growth and their handling.…”

The use of electrical devices has been increased tremendously around the world. Portable nickel-cadmium (Ni-Cd) batteries have been used in electronic products for many decades and have resulted in the generation of huge amounts of waste batteries. The battery disposal in municipal solid waste has become a serious problem for many countries. A battery can be considered as a recyclable material due to its high metal content and cannot be dumped directly in landfills, both for environmental and economic reasons. Amongst the metals present in Ni-Cd batteries, Cd is a toxic heavy metal harmful to both humans and environment. However, Ni and Co are valuable metals as a result of a decrease in their reserves and consequent increase in trading prices. Their disposal not only causes the loss of valuable metals but also demands the expenses for new material. Consequently, these spent batteries can be used as a secondary source for metals. The recycling of spent batteries is a growing industry. This review assesses the biohydrometallurgical process for recovery of metals from spent Ni-Cd batteries.

“…In contrast, the spent batteries always contain high concentration of alkaline matter or toxic compounds as oxides or hydroxides which greatly harm growth and activity of leaching cells. As a result, the pulp density was often only 1% or lower in bioleaching of the spent batteries [14][15][16]23], meaning that a significant quantity of media and a great volume of reactor were required [2].…”
