gram of gold. However, tailings from this process are often repeatedly run through the ball mills. Each time more auriferous, or gold-laden, mercury flour is produced. Though less mercury escapes by this method, this type of amalgamation is also a significant source of pollution and loss of gold. Table 2 shows analysis of.
