[133] Total recoverable lead content of ore production reported, less lead content of Australian production in forms other than pig lead.
[134] Probably represents ore surplus rather than exports.
[135] Lack of proper balance in these totals shows error or incompleteness, or lack of comparability, due in part to lag in the statistics, which, however, show correctly the general situation.
The ownership or operative control of mines is a minor factor in the commercial control of the lead industry and in general is of importance only as determining the distribution of ore to smelters competing otherwise on nearly equal terms. Most of the large smelter interests engage in, or have subsidiaries engaged in, mining or have sufficient holdings in large mining companies to influence their smelting contracts. The actual basis of control of the industry is, therefore, often through combined ownership or control of mines and of reduction works.
The ownership or control of reduction plants has been the dominating factor in the commercial control of the industry. The production of each country in 1913, the principal lead reduction works of the world, and their affiliations and control are discussed below.
