Group 1 - A tragic incident occurred where six junior students from Northeast University fell into a flotation tank during an internship at Zhongjin Gold, resulting in their deaths [1][2] - The flotation tank is described as having a significant vertical height, making it difficult for individuals to escape once they fall in [15] - The flotation slurry contains corrosive substances and heavy metal ions, posing severe health risks upon contact, including skin burns and respiratory issues [19][23] Group 2 - The incident highlights a lack of safety measures, as the grid plate above the flotation tank was not adequately secured, despite previous safety concerns raised by students [28][30] - The company had previously announced a goal of achieving zero accidents in the flotation workshop by 2024, indicating a commitment to safety that was not reflected in practice [31] - The recent replacement of the grid plate, which should have lasted for ten years, raises questions about the quality of maintenance and inspection practices within the company [34][36] Group 3 - The incident reflects broader issues within high-risk industries, where safety protocols may be overlooked, leading to preventable tragedies [40][42] - The perception of mining and mineral processing as high-risk fields is reinforced by this incident, potentially affecting student interest and recruitment in these areas [45][46] - The company’s apparent indifference to safety concerns may suggest a troubling attitude towards the welfare of students and interns [47]
