6名学生遇难事故，涉事企业回应三大焦点问题

Core Viewpoint - The article discusses the tragic accident involving six students from Northeast University at the China National Gold Group's Inner Mongolia mining facility, focusing on the responses from the mining department regarding safety concerns related to the flotation process and the properties of the slurry involved in the incident [1]. Group 1: Safety Concerns - The flotation machine is designed to minimize mechanical hazards, with the motor and components structured to prevent injuries [3]. - The slurry from the Ulan Copper Molybdenum Mine has been tested multiple times and found to contain no toxic substances, with the pH maintained around 9 using an 8% lime slurry [4]. - The flotation agents used are classified as safe and environmentally friendly, with specific concentrations detailed for each agent [4][5][6][7][8]. Group 2: Slurry Temperature - The flotation process operates at normal temperatures, with no heating facilities added, and the slurry temperature has been monitored to range between 23.2°C and 31.4°C [9]. - The temperature is crucial for flotation efficiency and product quality, but the current process does not induce any significant heat, aligning with the monitored data [9].
