Smb how does it work
I am trying to better understand the process from a chemical standpoint. Thanks again for your insights. Lino Well-known member. Joined Nov 1, Messages 2, Location Israel. Thank you kadiver. I have 19 grams of gold powder that I assume is contaminated with at least some tin, lead and copper.
I plan to heat it red hot to oxidize any tin then repurify. I am trying for best purity. And thank you Lino That was the original answer I was looking for with this question. I used SMB for the first precipitaion. But Hoke, page , tells me I should use a different precipitant for repurificantion. I have not seen that mentioned in this forum and everyone seems to use only SMB. Any thoughts? Joined Oct 7, Messages 2, That was the original answer I was looking for with this question.

Is it a purple stain, or brown? Brown is a false positive from the smb. Sure, why not. Add a bunch of copper to the solution that gold has been precipitated from. Siphon off barren solution 5. Take the solids out of that container and add them to the gold powder that was reduced with smb 6, add enough HCl to cover the powder and warm it up a little bit 7.
Stir with vigor, be careful not to breathe the chlorine gas 9. After 20 minutes or so, when dissolving action has ceased, add another pipette of bleach.
Continue stirring until action stops again If there is still powder to dissolve, add 50 mL of HCl then another pipette of bleach After all the gold is dissolved, turn the heat up a little more. You want it to steam, but not boil!
That is important, boiling is not good Woft a bit toward you, if it smells like Cl, keep steaming, if it is not strong. Then turn off the heat and let it cool. Let it settle overnight, or filter until crystal clear. Also important Take your clear solution and add some smb that has been dissolved in water and filtered clear also - your gold should immediately begin to precipitate, do not over add the smb, do small additions of the aqueous sodium metabisulfite.
Ive noticed that adding too much can give a dark precipitant, but just the right amount will keep it a beautiful tan coloured powder.
Test the solution to see if there is still gold in it. If positive, add a little more smb, if negative, siphon it off to your stock pot a bucket with a LOT of copper in it to catch traces of PM's Wash the gold powder with HCl, no heat, just stirring.
Wash with water until neutral pH After washing is clear, and neutral pH is attained, slowly dry the gold in the beaker it should never leave the vessel it was precipitated in until it is dried and going in the crucible to melt After gold is dried, well, melt it up!
I think I covered everything in there, oh, nope, I didn't. After the gold is dissolved, before you let it settle, you need to add sulfuric acid to remove any lead chloride, which will turn to insoluble lead sulfate, which will be filtered off at step This is very important, as lead will make the gold brittle.
The subsequent model, SMB 2. Today, the Server Message Block protocol works in dialect 7. An open-source server, known as Samba, which enhances the SMB protocol was developed for Unix systems.
Different versions of SMB may be negotiated and subsequently implemented by the client and server prior to the start of a session. As a result of the increasing varieties of SMB, there has also been an increase in the performance level. Below, we have highlighted 4 essential features of Server Message Block. Over time, different versions of the SMB protocol have advanced the initial efficiency, security, scalability, and capabilities of the innovation.
Here, we will briefly elaborate on 7 of the notable variants of the Server Message Block protocol. As a client-side caching network, this innovation featured opportunistic Locking OpLock intended to decrease network traffic. Server Message Block 2. It introduced limited conversations in order to enhance performance, increased resiliency and scalability, and additional support for WAN acceleration. It replaced OpLock with the client OpLock leasing model. This was done in order to improve caching and enhance performance.
It also featured extra updates such as enhanced energy efficiency and large maximum transmission unit MTU support. The aim of this was to enable users with open files from a Server Message Block network to activate sleep mode. Server Message Block 3. It featured several additional important updates aimed at the improvement of management, security, backup, performance, and availability. Although there are wired routers that you can use, you can also select modern routers most of which typically supply wireless connection to the other components of your system.
All devices and systems on your Local Area Network can establish a connection to the internet through the router. A lot of routers have dual functionality as the LAN server and supply each computer with its individual IP address. The IP address is an identification number that enables the computers to transmit and receive messages to the server and other network computers. When selecting a router, be sure to choose one that has a built-in firewall; to protect your system from unauthorized access.
Considering the complexity that is involved in properly configuring routers, it is recommended that you hire the assistance of an IT professional. This will facilitate the quicker transfer of data and higher rates of response, especially if you frequently send or stream multimedia files. You also need to ascertain if your computers are compatible with Gigabit Ethernet, which utilizes Cat5e cables, or Fast Ethernet, which utilizes Cat5e cables.
Although there are swifter alternatives on the market, these Ethernet options are appropriate for several small business needs. Moreover, they are cost-effective compared to higher versions. Use Adaptors and Other Peripherals to Outfit Devices It is a must for every client computer to possess an adaptor that enables it to establish a connection to the wireless router. The majority of computers and laptops are equipped with both integrated wireless functionalities and Ethernet ports, while tablets and smartphone devices also have wireless capabilities.
However, if your device is lacking these inbuilt capabilities, then you can buy an adaptor separately. In most cases, routers are equipped with 4 Ethernet ports, which means you can also get a switch to extend the number of wired devices that can be connected. You can also make use of a hub to create more connections, however, it lacks the administrative features of the router switch. The OS enables you to automatically establish and launch a small network utilizing the homegroup capability, which can be found in the Control Panel under Network and Internet.
After creating the homegroup, you can share any resource, printer, or file on a connected computer by right-clicking on the icon for the file in question and clicking the Sharing option under Properties.
In the case of a bigger client-server network that is not supported by the homegroup, you will be required to create a different Windows server to manage the Server Message Block protocol. You have to select a system that can be set up with ease and provides seamless networking capabilities; a recommended option for small organizations is NAS network-attached storage , which does not only act as a server but also demands that you only activate your essential services and settings.
Parameters within the section define the share attributes. Refer to the smb. There are global parameters, security parameters, logging parameters, browser parameters, communication parameters, and share parameters.
There are also several graphical user interfaces to configure and manage Samba. Samba provides this share to make it easy for users to share their Linux home directories with a Windows system. The following is an example:. These settings prevent users other than the owners from browsing home directories while allowing logged-in owners full access.
The reload argument does not stop and start the smb service; it only reloads the configuration file. Use the systemctl command to configure the service to start at boot time. To access a share on a Linux Samba server from Windows, open My Computer or Explorer and enter the host name of the Samba server and the share name in the following format:. You can also map a network drive to a share name by using the same syntax.
