Apart from process flow charts, other flow charts include workflow diagrams, influence diagrams, data flow diagrams, and swimlane flowcharts. Also, flow charts are divided into three different types: high-level flow charts, detailed flow charts and deployment flow charts. These flow chart types are what we're going to discuss next.
Process flow diagrams (PFDs) are used in chemical and process engineering. These diagrams show the flow of chemicals and the equipment involved in the process. Generally, a Process Flow Diagram shows only the major equipment and doesn't show details. PFDs are used for visitor information and new employee training. A Process and Instrument Drawing (P&ID) includes more details than a PFD. It
Flowchart guidelines to help you avoid 15 mistakes that you would unintentionally make when drawing flowcharts. Follow these flowchart guidelines to draw effective flowcharts.
Microsoft has a large number of Excel templates available online that make it easy to quickly create a good-looking and functional worksheet for any number of purposes. However, the easiest type of template to use to create a flowchart in Excel is SmartArt.
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted. There are two main
Five Tips for Better Flowcharts. Flowcharts can be an effective, efficient way to show steps in a process. But they can also be confusing and even misleading if not properly prepared. When designing and creating a flowchart, bear in mind that the diagram needs to be easy to understand. Here are five tips for good flowchart design. Applying them will allow you to make flowcharts that are easier

The Bayer process is basically used for the extraction of aluminum hydrate from the bauxite ores with the mass ratio of alumina to silica (A/S) above 9. The sinter process is widely used to process the poor-grade diasporic bauxite ores with A/S below 7, in China and Russia, by sintering the bauxite ore with sodium carbonate and limestone to form sodium aluminate and calcium silicate. In the
High-Level Flowchart for an Order-Filling Process. 2. Detailed Flowchart. Commonly Used Symbols in Detailed Flowcharts. One step in the process. The step is written inside the box. Usually, only one arrow goes out of the box. Direction of flow from one step or decision to another. Decision based on a question. The question is written in the diamond. More than one arrow goes out of the diamond
25.11.2017· The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). Bauxite, the most important ore of aluminium,
One way to achieve this is to restrict the number of processes in a data-flow diagram. Right Complexity for Human Mind - 7 + / - 2 Symbols. On lower-level data-flow diagrams with multiple processes, one should not have more than nine process symbols. Another way to avoid crossing lines is to duplicate an external entity or data store. Use a special notation such as an asterisk, to denote the
The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to bauxite mines and/or ports for efficient transport of raw materials and of the final
A Flowchart is a graphically representation of the process, algorithm or the step-by-step solution of the problem. There are ten types of Flowcharts. Using the Flowcharts solution from the Diagrams area of ConceptDraw Solution Park you can easy and quickly design the Flowchart of any of these types. Flow Chartin Detail And Types

The word flowchart has the same meaning as the words: flow chart, flow diagram, and flow sheet. The most popular are flow chart and flowchart. All are acceptable. See the tutorials: How to Draw a Flowchart; What do the different flowchart shapes mean? Drawing a Structured Flowchart
These flowchart examples can be downloaded and edited. It is sometimes easier to modify an existing chart than to draw a new one. Each chart is then a template for your own custom chart. It is sometimes easier to modify an existing chart than to draw a new one.
Flowchart examples. Make complicated procedures easy to follow. Flowcharts illustrate nearly any process in any industry—so whatever you're working on, having a flowchart maker in your toolkit is definitely a good idea.

BAYER PROCESS Bayer process is the process of refining alumina. from bauxite (aluminum ore containing 30-50% of hydrated aluminum oxide) by selective extraction of pure aluminum oxide dissolved in sodium hydroxide. Prior to the Bayer process bauxite is crushed and ground in mills to fine particles (max. size 0.06"/1.5mm). A hot solution of the recycled sodium hydroxide (caustic soda, NaOH
A flowchart is a type of diagram that represents a workflow or process.A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task.. The flowchart shows the steps as boxes of various kinds, and
19.03.2013· If you re starting a detailing or car wash business, and looking to add new services to increase your income or expand an existing business or simply considering a new and extremely profitable
If more than the most basic flowchart symbols appear in your diagram, it is good practice to include a legend or symbol key. Most flowcharts should be built using only the Start/End and Action or Process symbols and should follow a very basic set of best practices. Sticking with these two primary flowchart symbols is the best way to ensure that
4. EXISTING WAGERUP REFINERY 4.1 ALUMINA REFINING PROCESS As with the majority of other commercial alumina refineries throughout the world, the Wagerup refinery uses the Bayer process to refine alumina from bauxite ore. This involves a number of key steps, including: • Bauxite grinding; • Slurry storage; • Digestion; • Clarification; • Precipitation; and • Calcination. A simplified
Other articles where Bayer process is discussed: alumina: extracted from bauxite through the Bayer process, which was developed for the aluminum industry in 1888. In the Bayer process bauxite is crushed, mixed in a solution of sodium hydroxide, and seeded with crystals to precipitate aluminum hydroxide. The hydroxide is heated in a kiln in order to drive off
