A.D.L Gold Recovery Dredges are designed to comply with the specific requirements of the client’s project. The onboard treatment plant which incorporates radial and rectangular jigs is designed to maximise recovery efficiency.

Bucket capacities can range from 85 to 1,000 litres with maximum annual throughputs of 8,500,000 cubic metres when dredging to depths of 60 metres below the waterline.

Dredges can be supplied as turnkey projects or designed to maximise indigenous supply components if so required.

This A.D.L. designed dredge, which is one of four supplied to West Africa, is fitted with an overburden stripping facility and A.D.L. Pacemaker which facilitates instantaneous accurate bucket speed adjustment thus ensuring constant optimum loading of the treatment plant with resultant maximum recovery efficiency.
