Sample preparation is a critical aspect of assaying, as the accuracy of the results heavily relies on the careful selection and preparation of the ore sample. The goal is to ensure that the sample is representative of the entire bulk ore. This involves reducing the sample size either manually or using automated machines, with successive reductions to achieve finer particle size.

Sample Preparation in mineral labs involves collecting samples from mines or mine-derived products (e.g., raw ore, concentrate, tailings, slag) based on specific criteria. The goal is to analyze physical and chemical properties, addressing geological, mining, metallurgical challenges, and establishing a foundational dataset. It is the essential process of extracting a representative portion for subsequent analysis from a larger quantity, ensuring an accurate portrayal of the material’s characteristics.
