Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable. Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below)

gcse chemistry - extraction of copper - thermal

The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated. Thermal decomposition is an endothermic reaction. copper(II) sulfide      copper  +  sulfur dioxide CuS(s)                           Cu(s)       +       SO2(g) The impure copper which results is called blister copper. The disadvantage of this method is that it uses a lot of energy. If sulfur dioxide escapes into the atmosphere it causes pollution. The advantage is that it is fast

Bioleaching. Some bacteria can live by using the energy of the bond between sulfur and copper. This separates the metal from the ore and is called bioleaching. It has the advantage that it is very energy efficient typically using only 30% to 50 % of the traditional method. It has the disadvantage that it is very slow

Phytomining. Some plants absorb metal compounds (including copper) when they grow. The plants can then be burned and the metal is extracted from the ash. The process is called phytomining and it can also be used to extract metals from contaminated land. Brassicas (the cabbage family) can extract metals including cadmium, cobalt and nickel

what is a process flow diagram | lucidchart

Lucidchart is the best process flow diagram software available because it offers extensive features and shapes relevant to every industry trying to map out the process flow for any type of department, campaign, or means of standardization for a company or team. Learn the essentials of process flow diagrams (PFD), including the history, benefits and helpful tips with this guide. 

A Process Flow Diagram (PFD) is a type of flowchart that illustrates the relationships between major components at an industrial plant. It's most often used in chemical engineering and process engineering, though its concepts are sometimes applied to other processes as well. It’s used to document a process, improve a process or model a new one. Depending on its use and content, it may also be called a Process Flow Chart, Flowsheet, Block Flow Diagram, Schematic Flow Diagram, Macro Flowchart, Top-down Flowchart, Piping and Instrument Diagram, System Flow Diagram or System Diagram. They use a series of symbols and notations to depict a process.  The symbols vary in different places, and the diagrams may range from simple, hand-drawn scrawls or sticky notes to professional-looking diagrams with expandable detail, produced with software

This type of diagram has its roots in the 1920s. In 1921, industrial engineer and efficiency expert Frank Gilbreth, Sr. introduced the “flow process chart” to the American Society of Mechanical Engineers (ASME).  Over the next several decades, the concept spread throughout industrial engineering, manufacturing and even business, in the form of Business Process Diagrams, and information processing, in the form of Data Flow Diagrams and other chart types.

The most common PFD symbols in use today come from agencies such the International Organization for Standardization (ISO 10628 – Flow Diagrams for Process Plants, General Rules), the German Institute for Standardization (DIN) and the American National Standards Institute (ANSI.) However, many companies use their own symbols, which are often similar but vary as they become more detailed

When the diagram needs to show multiple unit processes at a plant, it becomes more of an overview, containing less detail. These are also called Block Flow Diagrams and Schematic Flow Diagrams. Each block can depict a single piece of equipment or a stage in a process. A rectangle is usually used to show a piece of equipment and labels illustrate function.  The process flow is usually shown from left to right, and arrows show flow direction

On the other hand, a Piping and Instrument Diagram (P&ID) is more technical, describing mechanical details for piping designers, electrical engineers, instrument engineers and other technical experts who need this detail more than they need process details. P&IDs take the conceptual aspects of a PFD and add detail about the equipment, process sequence, process and utility piping, bypass lines, instruments, valves, vents, drains and other items

For an advanced process such as at an industrial plant, the research may be done through a project team, quality control group or a consultant. For a smaller, more basic process, you might do this yourself, perhaps even starting with sticky notes

Study the equipment, activities and relationships through observation and interviews. If you’re modeling a brand-new process, study whatever data is available, including standards for whatever is being produced in the process

These diagrams can have a lot of value for even a basic process. If you’re new to PFDs, try it out, gathering sufficient detail for your purpose. Don’t worry about the chart itself at first. Just capture the information on sticky notes or sheets of paper

Move on to diagram software once you have your information. With intuitive software like Lucidchart, it’s not hard to create professional-looking diagrams to clearly communicate a process flow to your colleagues. The software also may help you to highlight missing data in your diagram

Be consistent with your symbols to avoid confusion. Remember who your intended audience is, and do whatever makes the most sense to give them what they need for the intended purpose. If you’re using diagram software, it will include a set of symbols to use

With Lucidchart, you have an intuitive platform for creating Process Flow Diagrams. Use our categorized library of symbols to easily build your diagram into a professional presentation.  It’s also easy to collaborate with colleagues with our platform, rather than trying to email charts back and forth. Permissions can be set to viewing, commenting or editing, in order to maintain control over the diagramming

The heart is a large muscular organ with the very important job of circulating blood through the blood vessels to the body. Located in the center of the chest, the heart is the hardest working muscle in the human body — always working, even while we are sleeping. The heart and blood vessels together make up the body's cardiovascular system and are vital to supplying the body with the necessary oxygen and nutrients needed to survive. When you breathe, your lungs take in oxygen. The heart pumps blood to the lungs to pick up oxygen, and then it pumps blood through the body to deliver that oxygen

A heartbeat is caused by an electrical impulse traveling through the heart. The heart's built-in electrical system controls the speed of its pumping. The electrical impulse originates in the sinus node which functions as the heart's natural pacemaker. The sinus node is most often located in the top of the right atrium. The electrical signals travel through the heart tissue causing the atria and ventricles to contract and relax and the blood to be pumped to the body
