1. Connect one end of each alligator clip to the terminals of the battery. The battery is what actually produces the electrical current and so the alligator clips provide the pathway for transporting that current to the water. You need to attach one clip to the positive terminal and one to the negative terminal. [5]

$begingroup$ Extracting the minerals & metals from sea salts is possible, but it would be better to extract them from sea water, whilst dissolved than from dry salt. Most extractive primary metallurgical & chemical processes involve liquids. The reason why it hasn't been done on a commercial basis is due to the number of processes that would …

One effective way to eliminate copper from your tank is through water changes. Regular changes of about 15-20% of the water in your tank can help dilute and lower the copper levels. Another option is to use activated carbon. Activated carbon can absorb copper and other toxins from the water, reducing the amount of copper present …

Michael Anissimov. Yes, it is possible to extract gold from seawater in theory, but it's really not practical to do so. It is estimated that there is, in total, about eight million tons of gold dissolved in the world's oceans. While this is a lot, the oceans are huge, and the actual concentration of gold in seawater is only about 0.0000000006%.

Scientists have long known that uranium dissolved in seawater combines chemically with oxygen to form uranyl ions with a positive charge. Extracting these uranyl ions involves dipping plastic fibers containing a compound called amidoxime into seawater. The uranyl ions essentially stick to the amidoxime. When the strands become saturated, …

Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides. The oxides are smelted to produce matte, which then …
