why to load carbon with gold and after strip off gold from carbon by electrolysis. is there any research to bypass the carbon loading and directly use the pregnant water as an electrolyte to recover gold ?

The use of CIL/CIP is no just to collect the dissolved gold but to collect it before natural carbons sometimes found in ores collect it. This is why is it called Activated Carbon. It should generally attract gold to it faster than natural organic carbons.

Merrill Crowe is the alternative.

Your idea of direct electrowinning of the pulp.... hmmm... no. Cost and other PhD like discussion.
