In 1818, the Cornish Copper Co sought to prevent Henry Harvey from constructing a new quay at Hayle, hundreds of workmen from both sides became involved and an actual clash was only narrowly avert.
In 1829, the dispute between Harvey and Co of Hayle and the Cornish Copper Company again flared over the ownership of the quay and land at Hayle. This was the culmination of years of acrimonious competition between the two companies, with channel diversions, poaching of workers and sharp practices, including the riots in 1818.
After a long legal battle, concerning the St Erth/Phillack boundary line, in 1832 the Harvey's were granted a portion of the quay, which had overlapped into St Erth and Harvey's property.
1832 'Last week a communication opened between the Cornish Copper Company's south and north quays, at Hayle over beautiful cast-iron drawbridge. The bridge was manulactured at the Company's foundry, is 10 feet wide, and 65 feet long, and is sufficiently strong for maintaining any weight that may he necessary to pass over it. Shipping will derive great advantage from the use of this bridge, vessels will not in future be required to come above the flood-gates, either to discharge or take in their cargoes.' 
The Cornish Copper Company also entered into direct competition with Harvey's in another sphere, iron-founding and the manufacture of Cornish Beam Engines.
The conflict, which divided Hayle into two warring camps, was not finally resolved until 1867, when the Copper Company - then Sandys, Carne and Co - sold out to Harvey's, which thereby gained sole control of the harbour.
