Abstract
Problem Statement (Relevance): The authors of this article demonstrate how important it is to monitor the size distribution of the concentrate in a timely manner for proper control over ore preparation and for better efficiency. Objectives: The authors aim to improve the process of taking and preparing samples for the size distribution analysis. Methods Applied: Methods applied included laboratory and field tests followed by the comparison of results obtained for samples taken using different sampling techniques. Originality: The original features of this research include the use of a combined method of sampling and sample preparation which helps eliminate the likely systematic error. Findings: To ensure accuracy of the size distribution analysis and to understand how successful a new ore preparation technology has turned to be, one should account for the likely systematic error by sampling consistently in order to register any possible local change in particle size distribution. Practical Relevance: This research resulted in the implementation of a new sampling equipment which utilizes a combined method of sampling and sample preparation. The use of this method can improve the judgement of how the current size distribution can impact the ore preparation and downstream processes.
