Explore the "Process Risk Assessment Template", a dynamic workflow that guides through the systematic identification, analysis, ranking, and mitigation of process-related risks. 1. Identify process to be assessed. Identify stakeholders involved in the process. Gather all relevant documentation related to the process.

The occurrence of mercury (Hg) in the environment globally has been linked largely to its use for gold processing. In this research, ore samples, agricultural soil and mine wastes were taken within the vicinity of an artisanal gold mine and processing sites in Niger state, a north-central part of Nigeria to determine Hg contamination in the environment and …

The results showed that the stage of gold processing work in ASGM consists of 13 sources of hazards that can pose 16 risks. The obtained risk assessment results showed that 19% were low risk, 31% moderate risk, 25% high risk, and 25% very high risk caused by exposure to mercury through the gold ore burning process with a risk value of 25.

Assess the severity of the consequences on the overall process if the risk materializes. Consider the financial, reputational, operational, and legal aspects. Share your estimation of the potential impact for each identified risk. Assessment of Likelihood. Assess the likelihood or probability of each identified risk occurring.

As part of a process of developing a risk management framework for ASGM, this paper reviews the common mining alternatives and criteria for their selection, and demonstrates a methodology for choosing an optimum technique. ...
