N2 Imaging Systems - Day 2 – Lot Catalog. Lot Closings: Lot Closings: The Lots will have a staggered closing time with 2 closing every minute in numerical order. For Example: Lots 1 and 2 will start to close at 10:00 AM, Lots 3 and 4 will start to close at 10:01 AM and so forth. (On the day the auction is set to close, each lot will clearly countdown the time left until closing.)

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
