Lead smelting - Wikipedia

Plants for the production of lead are generally referred to as lead smelters.Primary lead production begins with sintering.Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal.

Potential factors for determining a lead's score include demographic information and behavioral activity. This information is important and useful to the efficiency of passing off qualified leads because:

Lead Time vs. Cycle Time | iSixSigma

Lead Time and Cycle Time are two important metrics in Lean and process improvement in general. However, many people do not seem to understand the difference and their relationship. In fact, many use them interchangeably. This can lead to confusion in understanding the true problems in a process, and worse, poor decisions in process improvement.
