A STARTER SOLENOID (OR STARTER RELAY) IS THE PART OF AN AUTOMOBILE WHICH SWITCHES A LARGE ELECTRIC CURRENT TO THE STARTER MOTOR, IN RESPONSE TO A SMALL CONTROL CURRENT, AND WHICH IN TURN SETS THE ENGINE IN MOTION. ITS FUNCTION IS THUS IDENTICAL TO THAT OF A TRANSISTOR, BUT USING AN ELECTROMAGNETIC SOLENOID RATHER THAN SEMICONDUCTOR TO PERFORM THE SWITCHING. IN MANY VEHICLES THE SOLENOID ALSO ENGAGES THE STARTER PINION WITH THE RING GEAR OF THE ENGINE.

Lead anode mud generally contains less gold and does not contain platinum group metals, but contains high lead. Nickel anode mud is mainly platinum group metal except for a small amount of gold and silver. It can effectively capture gold and silver. In production, lead anode mud or nickel anode mud is usually mixed and smelted together with copper cation to recover valuable metals.
Cu, Pb, Ni electrolytic anode mud metallurgical fire is basically the same, because the most complex component of the copper anode slime, the longest production process employed. Which process is roughly divided into: copper removal off selenium, lead smelting reduction expensive to produce, expensive to produce lead oxide refining of gold-silver alloy, silver silver electrolytic refining separation, and electrolytic refining gold and platinum group metals recovery and the like.
