  NONTITANIFEROUS 
  MAGNETITES 
  

  

  General 
  relations 
  and 
  distribution 
  

  

  The 
  class 
  of 
  so 
  called 
  nontitaniferous 
  magnetites 
  includes 
  the 
  

   ores 
  that 
  are 
  relatively 
  free 
  from 
  titanium. 
  The 
  term 
  nontitan- 
  

   iferous, 
  it 
  may 
  be 
  noted, 
  is 
  hardly 
  an 
  accurate 
  one 
  to 
  apply 
  to 
  any 
  

   of 
  the 
  Adirondack 
  magnetites, 
  since 
  the 
  presence 
  of 
  titanium 
  has 
  

   been 
  shown 
  to 
  be 
  almost 
  universal 
  in 
  these 
  ores. 
  For 
  practical 
  

   purposes, 
  however, 
  the 
  low-titanium 
  magnetites 
  may 
  well 
  come 
  

   under 
  such 
  designation, 
  since 
  they 
  carry 
  an 
  inconsiderable 
  pro- 
  

   portion 
  of 
  the 
  element 
  — 
  usually 
  but 
  a 
  fraction 
  of 
  one 
  per 
  cent 
  — 
  

   too 
  small 
  to 
  have 
  any 
  notable 
  influence 
  on 
  their 
  metallurgical 
  

   behavior. 
  The 
  titanium 
  is 
  traceable 
  usually 
  to 
  the 
  mineral 
  titanite 
  

   which 
  is 
  a 
  common 
  constituent 
  of 
  the 
  wall 
  rocks 
  and 
  is 
  often 
  inter- 
  

   grown 
  with 
  the 
  magnetite. 
  Its 
  proportion 
  is 
  generally 
  higher 
  in 
  

   crude 
  ore 
  than 
  in 
  concentrates, 
  the 
  titanite 
  being 
  removed 
  to 
  a 
  

   greater 
  or 
  less 
  extent 
  by 
  mill 
  treatment. 
  

  

  The 
  nontitaniferous 
  magnetites 
  are 
  the 
  most 
  widespread 
  of 
  the 
  

   Adirondack 
  iron 
  ores. 
  They 
  have 
  been 
  worked 
  at 
  a 
  great 
  num- 
  

   ber 
  of 
  localities 
  distributed 
  over 
  different 
  sections. 
  

  

  With 
  some 
  exceptions 
  the 
  deposits 
  may 
  be 
  grouped, 
  however, 
  

   into 
  two 
  geographical 
  regions. 
  The 
  • 
  first 
  and 
  more 
  important 
  

   is 
  that 
  lying 
  on 
  the 
  eastern 
  border 
  of 
  the 
  Adirondacks 
  within 
  

   the 
  Lake 
  Champlain 
  drainage 
  basin. 
  To 
  this 
  region 
  belong 
  the 
  

   deposits 
  of 
  Washington 
  county, 
  the 
  Hammond 
  ville 
  and 
  Mineville 
  

   districts 
  and 
  the 
  smaller 
  mines 
  of 
  Essex 
  county, 
  and 
  all 
  of 
  the 
  

   mines 
  of 
  Clinton 
  county 
  aside 
  from 
  the 
  Lyon 
  Mountain 
  group. 
  

   The 
  last 
  named 
  is 
  the 
  only 
  one 
  on 
  the 
  north 
  side 
  of 
  the 
  Adiron- 
  

   dacks 
  that 
  has 
  been 
  exploited 
  to 
  any 
  extent, 
  though 
  there 
  are 
  a 
  

   few 
  small 
  bodies 
  in 
  Franklin 
  county. 
  The 
  second 
  region 
  lies 
  on 
  

   the 
  west 
  side 
  in 
  St 
  Lawrence 
  county 
  and 
  includes 
  the 
  Benson, 
  

   Jayville, 
  Fine 
  and 
  Clifton 
  deposits 
  all 
  lying 
  in 
  the 
  same 
  vicinity. 
  

   The 
  rest 
  of 
  the 
  western 
  border 
  extending 
  through 
  Jefferson, 
  Lewis 
  

   and 
  Oneida 
  counties 
  contains, 
  so 
  far 
  as 
  known, 
  no 
  deposits 
  of 
  size. 
  

   On 
  the 
  south 
  side 
  the 
  Salisbury 
  mine 
  of 
  Herkimer 
  county 
  is 
  the 
  

   single 
  representative. 
  

  

  Attention 
  has 
  been 
  called 
  by 
  Smock 
  and 
  other 
  writers 
  to 
  the 
  

   fact 
  that 
  nearly 
  all 
  of 
  the 
  mines 
  occur 
  in 
  the 
  bordering 
  zone 
  and 
  

   that 
  comparatively 
  few 
  have 
  been 
  opened 
  in 
  the 
  interior 
  of 
  the
