and process development they can all be included in the feasibility report for top management. 5.2 The design process The design activities are grouped into steps: 'getting the feel', screening, ball-park studies, optimisation and scale-up of production and marketing, leading at the end to product and


An example of jig is when a key is duplicated, the original key is used as base for the path reader which guides the movement of tool to make its duplicate key. The path reader of a CWC machine here works as a jig and the original is called template. Sometimes the template and jig both are the name of same part of a manufacturing system. Objectives


this Technical Resource Document. The use of the terms "extraction," "beneficiation," and "mineral processing" in this document is not intended to classify any waste stream for the purposes of regulatory interpretation or application. Rather, these terms are used in the context of common industry terminology.


jig's primary purpose is to provide repeatability, accuracy, and interchangeability in the manufacturing of products. A device that does both functions (holding the work and guiding a tool) is called a jig. An example of a jig is when a key is duplicated, the original is used as a jig so the new key can have the same path as the old one.

Rocks are generally composed of an assemblage of minerals. For example, the andesite from Mars contains quartz, feldspar, amphibole, and other minerals. Minerals can be divided into their constituent elements. The mineral quartz is composed of two elements, silicon and oxygen. Other minerals may contain many elements. For


Document control is the process used to maintain documents that control the design, operation, maintenance, and configuration of the site. Records management is the process for providing evidence of those activities. The utility quality assurance program will rely on N45.2.9/NQA-1 for records, but similar detailed guidance
