A process map is a planning and management tool that visually describes the flow of work. Using process mapping software, process maps show a series of events that produce an end result.A process map is also called a flowchart, process flowchart, process chart, functional process chart, functional flowchart, process model, workflow diagram, business flow diagram or process flow diagram.
Diamond processing To the non-professional, an unpolished rough diamond appears to be very much like a dull piece of glass. Only when it is polished and facetted, it ascends to its full glory, displaying the sparkling brightness and splash of colours for which it is famous.
Stage 2: Cleaving/Sawing a Rough Diamond. Copper disc embedded with diamond dust sawing a rough diamond. The cleaving process is the part that involves splitting the rough into separate pieces.This will then allow the cutter to work on the pieces separately and also to utilize the rough fully.
Jewelry polishing is a multistage process whereby metal is buffed with soft rotary tools made from bristles, felt, or muslin. Applied in descending stages, from coarse to fine, wheels are charged with various polishing compounds to achieve the desired luster.
The determination of what information makes its way through the different stages depends on what you pay attention to and process. Information that you pay attention to and process will move to the next stage of memory. However, any information you to do not pay attention to never makes it way to the next stage. Stages of Memory
Processing Methods. Although there are a number of different diamond recovery technologies being utilized worldwide, the two principal types are Rotary Pan plants and Dense Media Separation (DMS). Both methods are in actual fact used for bulk material reduction and require a further process for the final diamond recovery.
Diamond mining is a feat which requires precision, care, heavy duty extraction tools, and a substantial amount of monetary investment in machinery, to extract gems from the depths of the planet's crust. As a process, it consists of locating possible diamond deposits and their retrieval, in intact form.
As the mining process moves along in a horizontal fashion, the removed overburden is again deposited to fill over the excavated sites. Below-ground mining of kimberlite for diamond also requires moving enormous quantities of rock and other material in order to unearth gems, but on …
Stage 2 is a blend of high percentage natural chemicals and a high grade nano ceramic, which leaves a tough yet flexible coating. This product is the concentrated part of the process. It is an O/W (Oil-in-water) emulsion containing the main part of the protective coating and is applied directly onto the semi-cured Stage 1.
The Stage Gate Process focusses on product innovation and is used as a project management tool. It has different stages and gates, used in a project.
Stage 5 – Cleaned, weighed and packaged. The diamonds collected in the recovery process are cleaned in an acid solution, washed, weighed and packaged in sealed containers for transport. In accordance with the Kimberley process, these containers are sealed with a tamper resistant seal, numbered on site, and a certificate of origin is issued.
This methodology is very well-known and new. The double diamond is one way of showing the design process, illustrating how designers work through four key stages: Discover, Define, Develop and Deliver. "First, they expand space for lots of different ideas to be discovered and shared.
Sep 01, 2016· The New Double Diamond: Design in Action Published on ... The four phases of the Double Diamond may be simplified and merged into two main stages of the process. Stage …
Stages of Mediation. Many people think that mediation is an informal process in which a friendly mediator chats with the disputants until they suddenly drop their hostilities and work together for the common good. It doesn't work this way. Mediation is a multi-stage process designed to get results.
The final stage involves thoroughly cleaning the diamond in acids, and examining the diamond to see whether it meets the quality standards of the manufacturer. Cutting process It is possible only because the hardness of diamond varies widely according to the direction in which one is trying to cut or grind.
At the heart of the framework for innovation is Design Council's design methodology, the Double Diamond – a clear, comprehensive and visual description of the design process. Launched in 2004, the Double Diamond has become world-renowned with millions of references to it on the web.

This is a Diamond Processing Chart as it was done in the 1950s. World demand and production of diamond both for gem and industrial purposes has increased nearly five-fold during the past 25 years. Improved mining and recovery methods together with the discovery and development of new fields has enabled mining operations to fill the growing demands. Producing areas in Canada, South Africa ...
Jul 28, 1992· The invention teaches a deep boiling process for refining diamonds, be they raw or cut and polished. The process provides for initially precleaning the diamonds with solvents including alcohol, acetone, sulfuric acid, hydrogen peroxide, and/or water, to remove surface oils, hydrocarbons and other common surface impurities therefrom.
Strategies, plans, stages, steps, logical relationship and interconnections can be illustrated using the PowerPoint template. Diamond Process Template PowerPoint and Keynote Template is a six-stage linear diamond procedure flow diagram. The template can be used to represent the concepts of the business process.
This step lays the foundation for the potential of the diamond's performance because it establishes the diamond's basic symmetry. During the blocking stage, the first 17 or 18 facets are made, those facets being table, culet, and first eight facets on the crown and pavilion, creating what is known at this stage as a "single cut" diamond.
Final Recovery Methods. After processing the diamond bearing material in to concentrated form, final recovery of the diamonds is done by taking advantage of two further unique physical properties of diamonds – that they are hydrophobic, and that they fluoresce when exposed to x-rays.
Concentrating process: rotary mixers, agitators, jigs, cyclones, cones, heavy-media separators (industrial mining only) are used to achieve density separations. Collecting diamond process is done using grease table or x-ray separators. Final separation and sorting is done visually.
