As(III)-Domesticated HQ0211 Mix Bacterial and Archaeal Culture in Pretreatment of Arsenic-Bearing Refractory Gold Ore
Abstract According to current statistics, one-third of the world’s total gold output comes from refractory gold ores. These types of ore pose a very different challenge to producers. One of the contributors to refractory behaviors is arsenic which causes refractoriness even at low concentration. To...

| 520 | |a Abstract According to current statistics, one-third of the world’s total gold output comes from refractory gold ores. These types of ore pose a very different challenge to producers. One of the contributors to refractory behaviors is arsenic which causes refractoriness even at low concentration. To improve the arsenic resistance of the bioleaching strains is very necessary and important for the treatment of arsenic-bearing refractory gold ores. In this paper, HQ0211 mix microbial culture was used to study bio-oxidation of arsenic-bearing refractory gold ore after domestication in As(III) environment. The oxidation effect was measured by determining the redox potential, pH, concentration of $ Fe^{2+} $ (g $ L^{−1} $), dissolved arsenic (%) and concentration of the mix microbial strains. It was found that HQ0211 mix microbial strains oxidized $ As^{3+} $ to $ As^{5+} $ efficiently. In order to reduce the harmful effect of arsenic to the growth of the strains, about 65.52% of $ As^{3+} $ was oxidized to $ As^{5+} $ at the end of the oxidation process. The logarithmic period was the best period for the oxidation ability and stability of the strains. The HQ0211 mix microbial culture which had been domesticated by As(III) was suitable for the oxidation pretreatment of arsenic-bearing refractory gold deposits. On the other hand, separation of $ As^{3+} $ and $ As^{5+} $ was conducted. It was discovered that under strong acid condition, toluene could be used to extract $ As^{3+} $ while $ As^{5+} $ retained in the water phase. The content of $ As^{3+} $ was determined by iodine method. It was found that the acidity of the solution had a great influence on the extraction of $ As^{3+} $ by toluene. The total separation of $ As^{3+} $ and $ As^{5+} $ and the recovery rate were greater than 99%. The separation could be achieved when the concentration of HCl was greater than 10 mol $ L^{−1} $. | ||

These types of ore pose a very different challenge to producers. One of the contributors to refractory behaviors is arsenic which causes refractoriness even at low concentration. To improve the arsenic resistance of the bioleaching strains is very necessary and important for the treatment of arsenic-bearing refractory gold ores. In this paper, HQ0211 mix microbial culture was used to study bio-oxidation of arsenic-bearing refractory gold ore after domestication in As(III) environment. The oxidation effect was measured by determining the redox potential, pH, concentration of $ Fe^{2+} $ (g $ L^{−1} $), dissolved arsenic (%) and concentration of the mix microbial strains. It was found that HQ0211 mix microbial strains oxidized $ As^{3+} $ to $ As^{5+} $ efficiently. In order to reduce the harmful effect of arsenic to the growth of the strains, about 65.52% of $ As^{3+} $ was oxidized to $ As^{5+} $ at the end of the oxidation process. The logarithmic period was the best period for the oxidation ability and stability of the strains. The HQ0211 mix microbial culture which had been domesticated by As(III) was suitable for the oxidation pretreatment of arsenic-bearing refractory gold deposits. On the other hand, separation of $ As^{3+} $ and $ As^{5+} $ was conducted. It was discovered that under strong acid condition, toluene could be used to extract $ As^{3+} $ while $ As^{5+} $ retained in the water phase. The content of $ As^{3+} $ was determined by iodine method. It was found that the acidity of the solution had a great influence on the extraction of $ As^{3+} $ by toluene.

These types of ore pose a very different challenge to producers. One of the contributors to refractory behaviors is arsenic which causes refractoriness even at low concentration. To improve the arsenic resistance of the bioleaching strains is very necessary and important for the treatment of arsenic-bearing refractory gold ores. In this paper, HQ0211 mix microbial culture was used to study bio-oxidation of arsenic-bearing refractory gold ore after domestication in As(III) environment. The oxidation effect was measured by determining the redox potential, pH, concentration of $ Fe^{2+} $ (g $ L^{−1} $), dissolved arsenic (%) and concentration of the mix microbial strains. It was found that HQ0211 mix microbial strains oxidized $ As^{3+} $ to $ As^{5+} $ efficiently. In order to reduce the harmful effect of arsenic to the growth of the strains, about 65.52% of $ As^{3+} $ was oxidized to $ As^{5+} $ at the end of the oxidation process. The logarithmic period was the best period for the oxidation ability and stability of the strains. The HQ0211 mix microbial culture which had been domesticated by As(III) was suitable for the oxidation pretreatment of arsenic-bearing refractory gold deposits. On the other hand, separation of $ As^{3+} $ and $ As^{5+} $ was conducted. It was discovered that under strong acid condition, toluene could be used to extract $ As^{3+} $ while $ As^{5+} $ retained in the water phase. The content of $ As^{3+} $ was determined by iodine method. It was found that the acidity of the solution had a great influence on the extraction of $ As^{3+} $ by toluene. The total separation of $ As^{3+} $ and $ As^{5+} $ and the recovery rate were greater than 99%. The separation could be achieved when the concentration of HCl was greater than 10 mol $ L^{−1} $.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Mix microbial culture</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Domestication</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Oxidation rate</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Arsenic resistance</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Redox potential</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yang, Hongying</subfield><subfield code="0">(orcid)0000-0002-5161-7444</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Transactions of the Indian Institute of Metals</subfield><subfield code="d">[New Delhi] : Springer India, 2008</subfield><subfield code="g">73(2019), 1 vom: 18.

As(III)-Domesticated HQ0211 Mix Bacterial and Archaeal Culture in Pretreatment of Arsenic-Bearing Refractory Gold Ore |
| abstract |
Abstract According to current statistics, one-third of the world’s total gold output comes from refractory gold ores. These types of ore pose a very different challenge to producers. One of the contributors to refractory behaviors is arsenic which causes refractoriness even at low concentration. To improve the arsenic resistance of the bioleaching strains is very necessary and important for the treatment of arsenic-bearing refractory gold ores. In this paper, HQ0211 mix microbial culture was used to study bio-oxidation of arsenic-bearing refractory gold ore after domestication in As(III) environment. The oxidation effect was measured by determining the redox potential, pH, concentration of $ Fe^{2+} $ (g $ L^{−1} $), dissolved arsenic (%) and concentration of the mix microbial strains. It was found that HQ0211 mix microbial strains oxidized $ As^{3+} $ to $ As^{5+} $ efficiently. In order to reduce the harmful effect of arsenic to the growth of the strains, about 65.52% of $ As^{3+} $ was oxidized to $ As^{5+} $ at the end of the oxidation process. The logarithmic period was the best period for the oxidation ability and stability of the strains. The HQ0211 mix microbial culture which had been domesticated by As(III) was suitable for the oxidation pretreatment of arsenic-bearing refractory gold deposits. On the other hand, separation of $ As^{3+} $ and $ As^{5+} $ was conducted. It was discovered that under strong acid condition, toluene could be used to extract $ As^{3+} $ while $ As^{5+} $ retained in the water phase. The content of $ As^{3+} $ was determined by iodine method. It was found that the acidity of the solution had a great influence on the extraction of $ As^{3+} $ by toluene. The total separation of $ As^{3+} $ and $ As^{5+} $ and the recovery rate were greater than 99%. The separation could be achieved when the concentration of HCl was greater than 10 mol $ L^{−1} $. © The Indian Institute of Metals - IIM 2019 |
