 The economy of Clwyd depends on a mixture of industrial , agricultural and tourism activities , with tourism predominating . The land uses of any region depend on the underlying geology which influences the soil types . In the Clwydian Range , lead and spar minerals have been mined in the past , and limestone quarried from <unk> Mountain , Ruabon Mountain and Minera Mountain near Wrexham . The Minera <unk> were once the largest lime workings in North Wales . Later , road building stone was extracted but the quarries closed in 1992 . Coal mining in the North Wales Coalfield ceased in the second half of the twentieth century but used to be a large source of employment in the area . The main products being manufactured in industrial east Clwyd include aircraft components ( Airbus ) , engines ( Toyota ) , paper ( Shotton Paper ) and steel processing , and the port of Mostyn builds and supports offshore <unk> .
