The progression from the comminution till and gravelly mud of Units 3 and 2 into the diatomaceous mud of Unit 1 likely represents the Last Glacial Maximum to Holocene transition in the northwestern Weddell Sea.
Unit 3 (150–230 cm) consists of a structureless black mud with elevated shear strength, which represents a comminution till deposited under grounded ice (Domack et al., 2001a).
For though it be true that the most solid bodies have pores, still air or spirit do not easily submit to such extremely fine comminution, just as water refuses to run out at very small chinks.
The distinction is this: breaking is a division and separation into large parts, comminution into parts of any size, but there must be more of them than two.
In crabs, then, and in such other animals as are able to seize their food in a leisurely manner, inasmuch as their mouth is not called on to perform its office while they are still in the water, the two functions are assigned to different parts, prehension to the hands or feet, biting and comminution of food to the mouth.
For their claws are substitutes for hands, and so require to be suitable for the prehension of food, and not for its comminution; for such comminution and biting is the office of teeth.
- For all of the marketable hand-sorted pre-concentrates, further beneficiation efforts (comminution, classifying, sorting) are not necessary.
This type of middling product occurs even in the most precise separation processes, and valuable mineral so contained cannot be separated by further processing without additional comminution.
The tenacity describes the fracturing behavior (as opposed to cleavage or scratch (abrasive) hardness) of the mineral, and decisively governs the behavior of a mineral during comminution.
This is done through the separation of the simultaneous processes of amalgamation and grinding or comminution in pan grinders (as in Chile) or stamping mills (as in Ecuador and Colombia) using two procedural steps.
